AGENDA REQUEST & STAFF REPORT
For Board Business Meeting of July 23, 2008
Please see directions for completing this document on the next page.
DATE: July 9, 2008
FROM: Barbara Rich CDD x4713
TITLE OF AGENDA ITEM:
Consideration of Second Reading and Adoption of Ordinance 2008-012, Adopting the Proposed Local
Rule for Onsite Wastewater Treatment Systems in Southern Deschutes County.
PUBLIC HEARING ON THIS DATE? No.
BACKGROUND AND POLICY IMPLICATIONS:
This ordinance adopts Deschutes County Code Chapter 13.14, South County Onsite Wastewater
Treatment. Commonly known as the "Local Rule," this code would require the use of nitrogen
reducing systems for all onsite system permit applications in southern Deschutes County and require
the upgrade of existing systems by November 2022.
FISCAL IMPLICATIONS:
Deschutes County will generate some permit revenue above and beyond normal permit activity as
existing onsite systems are upgraded to nitrogen reducing systems.
RECOMMENDATION & ACTION REQUESTED:
Signature of Ordinance 2008-012.

STAFF REPORT
Public Hearing July 7, 2008
The Board will consider adoption of the proposed "Local Rule," under which all residential
properties in the unincorporated areas of South Deschutes County that are not currently served
by sewer systems would be required to upgrade their septic systems to reduce nitrogen
discharges, connect to sewer systems or take some other nitrogen -reduction measure within 14
years of the effective date of the ordinance.
Highlighted areas in the staff report indicate the significant changes from previous versions.
PROPOSAL: Consider adoption of a Local Rule to require the use of nitrate reducing onsite
wastewater treatment systems or other approaches to achieve the same level
of groundwater protection in south Deschutes County to protect the primary
source of drinking water and surface waters of the upper Deschutes River
watershed.
STAFF:
The proposal includes requirements that:
1. New development installs systems that are Maximum Nitrogen Reducing
Systems (defined as systems that achieve a minimum of 79% reduction in
total nitrogen and discharge a maximum of 10 mg/L total nitrogen);
2. Existing systems upgrade within 14 years of the date the rule takes effect;
3. Existing systems meet a variable nitrogen reduction standard established
by the USGS Nitrate Loading Management Model
Other programs interacting with the proposal include financial assistance
programs funded by the sale and development of land within the La Pine
Neighborhood Planning Area and state rules governing the expansion or
creation of sewers in rural areas.

11. BASIC FINDINGS:
A. Affected area: The areas affected by the proposal are unsewered areas between
Sunriver and the Klamath County border, this area is formally defined as those
unincorporated portions of Deschutes County contained in Townships 19, 20, 21, and 22
and Ranges 9, 10 and 11, except those areas authorized for sewer.
B. Affected uses: Uses affected by the proposal are those generating Tess than 2,500
gallons of residential strength wastewater per day.
C. Purpose: The goal of the proposed rule is to reduce onsite wastewater treatment
system pollutants, particularly nitrogen, discharged to the sole source aquifer in order to
maintain and improve public waters in the La Pine basin of the upper Deschutes River
watershed. The proposed rule applies only to those systems for which the County has
permitting authority (systems that generate Tess than 2,500 gallons per day of residential
waste strength wastewater).
D. History and background: South Deschutes County has been the focus of extensive
local, state and federal attention beginning in the early 1980s with the identification of
significant groundwater impacts from onsite wastewater treatment systems in the La
Pine Unincorporated Community. Provided below is a timeline of events related to water
quality in the region.
1960's
and
125 -square mile area of La Pine subdivided into over 12,000 lots

identify regional problems and evaluate solutions.
1997
Sewer Feasibility Study determined that creating or expanding sewers in
the study areas to cost between $19,000 and $28,000 per household. A
20 -year payback at 3% costs between $1,275 and $2,880 per household
per year. This estimate also assumed that the sewage treatment plant site
and related land could be purchased at $3,000 per acre.

Water Quality Directives resulting from Regional Problem Solving:
• Continue studying nitrates, well head protection, and alternative
sewage disposal systems.
■ Do not build a new sewer system in study areas
• Reduce residential density to meet the carrying capacity of onsite
sewage disposal systems through a market-based Transfer of
Development Credit Program
■ Identify areas where existing community sewer systems can be
expanded (La Pine Sewer District).
• Support Oregon Water Wonderland 11 (OWW2) efforts to upgrade
existing sewage treatment facilities for that subdivision
1999
Oregon DEQ received $5.5 million grant from US Environmental Protection
Agency to study the groundwater, model the aquifer, and field test nitrogen
reducing onsite systems
2000
Deschutes County Comprehensive Plan amended to include these goals in
response to public involvement during Regional Problem Solving:
1. To preserve water and air quality, reduce wildfire hazards and protect
wildlife habitat.
2. To ensure that domestic water derived from groundwater meets safe
drinking water standards.
3. To develop an equitable, market-driven system, that reduces the
potential development of existing lots in floodplains, wetlands, mule
deer migration corridors and areas susceptible to groundwater
pollution.
4. To create a new neighborhood, primarily residential in character,
between La Pine and Wickiup Junction, that provides services
efficiently, sustains economic development and reduces adverse
impacts to groundwater quality in South Deschutes County.
5. To explore innovative sewage treatment and disposal methods

The TDC Technical Advisory Committee recommends creating a Pollution
Reduction Credit program to work in conjunction with a local rule to require
the use of nitrogen reducing onsite wastewater treatment systems.
May 2006
The Planning Commission, after holding a public hearing in La Pine,
recommended that the Board of County Commissioners adopt
amendments to the Transferable Development Credit Program to create
Pollution Reduction Credits and financial assistance for homeowners
upgrading their existing onsite wastewater treatment systems to better
protect groundwater.

Page 4 of 35 — EXHIBIT "B" TO ORDINANCE NO. 2008-012 (7/9/08)
June
2006
The Board of County Commissioners adopted amendments to the
Transferable Development Credit Program to create Pollution Reduction
Credits.
E. Public involvement: The Community Development Department developed a public
participation plan to solicit comments and suggestions for the proposed Local Rule while
the Pollution Reduction Credit program was being established. The first phase of the
public participation process was to develop a notice of the Groundwater Protection
Project to include with all site evaluation and permit application materials. The
Environmental Health Division began distributing this notice with permit materials in
March 2006.
Next, the Department developed the first of a series of public information brochures
about the issues and proposal:
• Project Overview Brochure, Spring 2006
• South County Groundwater Protection History, Spring 2006
• Why Not Sewer? Brochure, Spring 2006
These brochures were first distributed at an open house for the opening of the South
County Services building and at the Home Show at the Deschutes County Fairgrounds
in May 2006.
Next steps included revising the Groundwater Protection Project website and initiating
meetings with area onsite system installers and realtors.
Further public information materials were developed in late summer 2006 with monthly
articles in the Newberry Eagle beginning in September 2007. Additional public
information materials were developed at this time including the following notices and
brochures:
• Notice of Planning Commission meeting, November 30, 2006
• Notice of Local Rule - Tax Bill Insert, October 2006
• Notice of Groundwater Protection Project (distribution began March 2006)
• Groundwater Protection Project Update, September 2006
• But my water was just tested! November 2006
• Pollution Reduction Credit Program Brochure, Fall 2006
The Tax Bill Insert was mailed to 10,243 property owners to provide individual notice of
the proposed rule. Following this the Department held a series of public meetings to
present the reason for the proposed rule and solicit comments and suggestions about
the Local Rule Concepts. The public meetings began with two events held at the La
Pine Senior Center:
• November 9, 2006 (requested by the La Pine Senior Center)
• November 30, 2006 (hosted by the Deschutes County Planning Commission)
The attendees at the November 30 meeting requested a session specifically for
reviewing the scientific basis of the proposed rule. This session was held December 20,
2006 and was presented as the Groundwater Science Open House with the USGS in
attendance to answer questions about the groundwater investigation and models. The
open house format was used to allow interested persons to move from station to station
and ask specific questions easily and quickly without having to wait through a lengthy
Local Rule for Onsite Wastewater Treatment Systems in South Deschutes County
Page 5 of 35 — EXHIBIT "B" TO ORDINANCE NO. 2008-012 (7/9/08)
presentation. The Department decided to use this format after receiving feedback from
the November 30 meeting that some attendees felt intimidated about asking questions in
the lecture format when audience members were loudly responding to questions and
answers.
The Department, following the Groundwater Science Open House, scheduled additional
office hours to provide more opportunities for interested persons to drop by and obtain
more information about the science or other aspects of the proposal. The Department
scheduled office hours each week in January 2007 on different days of the week and at
different times during the day. The variation in locations, times and days were in
response to comments that all the meetings were held in the southern portion of the
affected area and that they were being held in the evening. By mixing the days.
locations and times, Department staff intended to create opportunities for interested
persons to be able to attend at least one session. Unfortunately, times and locations for
the office hour sessions in the northern portion of the affected area were constrained by
the available space. As a result these sessions were made twice as long as the
southern sessions.
• January 4, 2007, 5:00 - 7:00, Deschutes County office, La Pine
• January 9, 2007, 1:00-5:00, Village Properties office, Sunriver
• January 18, 2007, 1:00-5:00, Village Properties, Sunriver
• January 23, 2007 3:00 - 5:00, Deschutes County office, La Pine
The Board of County Commissioners held a public hearing over three nights on March
13, 20, and 27, 2007 on the proposed rule. The Board closed the hearing on March 27th
but left the written record open for public comments. The Board re -opened the record
for verbal testimony on the amendments presented at the March 19, 2008 hearing. The
record was closed for verbal testimony at the end of the hearing and the written record
was left open until April 18, 2008. Because this is a legislative code amendment, the
Board has accepted all written testimony submitted after April 18, 2008.
The Board of County Commissioners held public work sessions with the Oregon
Department of Environmental Quality and the Oregon Department of Land Conservation
and Development on April 18, 2007 and January 30, 2008 to discuss the groundwater
science and modeling and next steps for protecting groundwater in the region.
The full list of notices, public information materials, and newspaper articles is available
as Appendix A. Appendix B provides a summary of the materials and information
provided at the Groundwater Science Open House. These materials were also provided
at the office hour sessions.
The Transferable Development Credit Technical Advisory Committee and the Deschutes
County Planning Commission have also been kept apprised of the Local Rule public
comment and participation process leading up the public hearing in March 2007.
On June 11, 2008, the Board of County Commissioners adopted Ordinance 2008-019 to
require the use of nitrogen reducing systems on all new development and existing
development at the time of major alteration (major house remodels or replacements) or
major repair at time of system failure. This ordinance acknowledges the existing Oregon
Administrative Rule that states that county permitting authorities acting on behalf of the
State, such as Deschutes County, may not authorize installation of a wastewater
treatment system that is likely to pollute public waters, but rather, must require the
installation of a wastewater treatment system that protects public waters or public health
(OAR 340-071-0130(1)). Ordinance 2008-019 is provided in Appendix C.

F. Public comments: As of this writing, the Department or the Board of County
Commissioners has been accepting public comments and inquiries on the proposal
Local Rule for nineteen months. The comments and inquiries are too numerous to
include (estimated 3,500 to 4,000 pages of material) in this report but are available for
review in the Community Development Department offices in Bend and La Pine or online
at http://www.deschutes.orq/cdd/qpp/ at the link to "Public Record for Local Rule." The
list below provides basic comment categories:
Cost: Affects on cost of living are too great, what kinds and quantity of financial
assistance are available, what is the cost of upgrades, what are cost
comparisons with other potential solutions, this will have a negative effect on the
real estate market, and ideas for additional financial assistance programs.
Science: What is the quantity and quality of science supporting the proposed rule, how
much sampling was conducted and where were the wells located, how was the
quality of the information assured, was the study design and the results peer
reviewed, what are the sources of nitrogen in the region, the proposal should be
to change drinking water wells instead of onsite systems.

clusters
Public Participation: How do interested persons receive notice of events, what is the
public participation plan, what is timing of events
DEQ jurisdiction: What are the treatment requirements for commercial and other large
systems, will Klamath County have requirements for their residents, how are
alternative systems approved, what are the Groundwater Management Area
requirements, why not adopt a Geographic Rule instead of a Local (County) Rule
Local Rule: What are the performance standards, what is the affected area, what is the
time period for upgrades, what are the standards for new development, what are

III. FINDINGS OF FACT:
A. Impacts to water quality from conventional onsite systems:
1. Aquifer -scale controls on the distribution of nitrate and ammonium in ground
water near La Pine, Oregon, USA. Hinkle, et al, Journal of Hydrology, (2007)
333, 486-503. (Available on the web at: http://or.water.usgs.gov/prof/or186/)
FINDING: In order for the US Geological Survey to have a paper accepted for publication in the
Journal of Hydrology, the manuscript must pass review in two stages. First, the manuscript
must pass review by the editors. The editors have the option of accepting, rejecting or
forwarding the manuscript for further review. Those papers rejected at this stage are
insufficiently original, have serious scientific flaws, have poor grammar or English language, or
are outside the aims and scope of the journal. Those that meet the minimum criteria are passed
on to at least 2 experts for more thorough scientific review. The expert reviewers, or referees,
are matched to the paper according to their expertise. The Journal of Hydrology uses single
blind review, where the referees remain anonymous throughout the process. Referees are
asked, among other considerations, to evaluate whether the manuscript:
• Is original
• Is methodologically sound
• Follows appropriate ethical guidelines
• Has results which are clearly presented and support the conclusions
• Correctly references previous relevant work
In summary, the findings of this paper have been reviewed by experts of national and/or
international standing in the field of hydrology and these experts found the paper to be
methodologically sound and produced results supporting conclusions that:
1. groundwater in the region is slow moving
2. the source of nitrate in the groundwater is septic tank effluent,
3. the source of ammonium in the groundwater is natural,
4. denitrification can occur in the aquifer at depths where oxygen has been depleted,
5. the nitrate contamination that has entered the aquifer so far is concentrated in the
most shallow portions of the aquifer and is slowly moving to greater depths
6. the typical drinking water well produces water that is older than development in the
region and therefore is generally not currently contaminated.
2. Evaluation of Approaches for Management Nitrate Loading from On -Site
Wastewater Systems near La Pine, Oregon. Morgan et al, 2007, USGS Scientific
Investigations Report 2007-5237. (Available on the web at:
http://or, water. usgs. qov/prof/or186/)
FINDING: The US Geological Survey, in partnership with Oregon DEQ, developed the three-
dimensional groundwater and nutrient fate and transport model for the La Pine sub -basin of the
Upper Deschutes River watershed. This model built on the groundwater study and model
developed for the Deschutes River watershed by Gannett, et al (2001 and 2004).
The three-dimensional model simulates the aquifer and its response to recharge from
precipitation, discharge to streams and wells and certain geochemical loads.
Local Rule for Onsite Wastewater Treatment Systems in South Deschutes County
Page 8 of 35 — EXHIBIT "B" TO ORDINANCE NO. 2008-012 (7/9/08)
Basic findings of the three-dimensional model are that:
1. using nitrogen reducing onsite systems can reduce the nitrogen load and protect the
aquifer;
2. using nitrogen reducing systems on new development alone won't adequately
protect groundwater quality;
3. upgrades occurring when systems fail or when houses are remodeled or replaced
(approximately 100/year) do not occur quickly enough to protect groundwater quality:
4. the aquifer's ability to remove nitrogen is incorporated into the model (via discharge
to rivers, pumping wells, or denitrification in the oxygen depleted portions of the
aquifer); and
5. time is of the essence in that as more development is allowed to occur without taking
action, more nitrogen enters the aquifer and more existing systems are created that
need upgrades.
Resource optimization is a technique used by the military to determine how many planes, tanks
etc. can be constructed with available resources (for example, steel). When this technique is
applied to natural resources (like the groundwater in the La Pine sub -basin), the resulting tool
tells us how much nitrogen can be allocated to various locations with the region given the
different characteristics of each area.
The US Geological Survey (Morgan et al, 2007), developed the Nitrate Loading Management
Model by linking resource optimization methods to the three-dimensional simulation model.
This model provides a tool that can be used to evaluate alternative strategies for managing
nitrate loading to the shallow groundwater system. This model allows resource managers to
identify the desired outcome (for example, groundwater meets the Oregon groundwater quality
standard action level of 7 mg/L) and obtain, as a model output, the performance standards that
need to be met to achieve that desired outcome (for example, area X needs to meet a
performance standard of 58% to 78% reduction). Because this model can produce variable
performance standards by area, it can help keep the cost for upgrades to existing systems as
low as possible by avoiding a requirement that all systems install the highest level of treatment
available.
The findings of this study are summarized in US Geological Survey Fact Sheet 2007-3103
entitled, "Questions and Answers About the Effects of Septic Systems on Water Quality in the
La Pine Area, Oregon," (Williams et al, 2007).
Peer review processes for USGS Scientific Investigations Reports are comparable to the peer
review processes described above for the Journal of Hydrology paper. As a result, staff finds
that hydrogeologic expertise of both national and international caliber has reviewed the work
embodied in this report and determined that it is scientifically rigorous and defensible.
3. Ground Water Redox Zonation near La Pine, Oregon: Relation to River Position
within the Aquifer -Riparian Zone Continuum. Hinkle et al, 2007, USGS Scientific
Investigations Report 2007-5239. (Available on the web at:
http://or. water.usgs.gov/prof/or186/)
FINDING: This study was initiated in order to study how nitrogen enriched groundwater can enter
nitrogen -limited surface water bodies in the upper Deschutes River watershed. Additions of
nitrogen to nitrogen -limited rivers can lead to increases in primary productivity (for example, algae
and aquatic plant growth) which then can reduce dissolved oxygen and change pH levels in the
Local Rule for Onsite Wastewater Treatment Systems in South Deschutes County
Page 9 of 35 — EXHIBIT "B" TO ORDINANCE NO. 2008-012 (7/9/08)
river. Significant declines in dissolved oxygen have lead to fish and other aquatic life kills in other
similarly affected water bodies. This study found that oxic (and potentially nitrate -rich)
groundwater can enter rivers in south Deschutes County, which means that there are areas where
rivers are vulnerable to impacts from increased nitrogen loading if no corrective action is taken.
4. Drinking water well tests at time of property sale.
FINDING: Thirty-one percent (31 %) of 8,756 samples collected from private drinking water
wells at the time of sale between September 1988 and November 2005 exceeded 1 mg/L nitrate
(exceeded background levels). The samples showing greater than background levels of nitrate
are shown in the table by concentration:
1 - 4.99 mg/L.
5.00 - 9.99 mg/L
>10 mg/L
2068
540
82
The samples equaling or exceeding 10 mg/L ranged from 10 to 72 mg/L.
This database, as received from the Oregon DEQ, contains multiple results reported for
individual properties because an individual property could have sold more than once during the
period between 1988 and 2005. In addition, the quality assurance/quality control of the sample
collection and analyses changed over time and could have changed from location to location.
There is no information available showing that sample collection and analysis protocols were
consistent over the record. While the dataset creates some concerns for the quality of data
presented therein, the dataset does show that, given the fact that onsite wastewater treatment
systems are the single largest source of nitrate in groundwater in the region, drinking water
wells can be and are impacted by onsite system effluent in the south Deschutes County region.
5. Drinking water well sampling in 2000.
FINDING: Oregon Department of Environmental Quality and Deschutes County Community
Development Department staff sampled a well network three times between June 2000 and
June 2001 as part of the La Pine National Demonstration Project. Data from these sampling
events showed 24% of the wells discharged water with nitrate concentrations greater than
background levels:
<1.0 mg/L.
1-6.9 mg/L
7.0-9.9 mg/L
>_10 mg/L

This dataset was collected in strict compliance with the Oregon DEQ's quality assurance/quality
control protocols and the laboratory analyses were conducted in compliance with the
Environmental Protection Agency's certification requirements for the DEQ lab, including specific
Local Rule for Onsite Wastewater Treatment Systems in South Deschutes County
Page 10 of 35 — EXHIBIT "B" TO ORDINANCE NO. 2008-012 (7/9/08)
quality assurance and quality controls specifications. Therefore these data are considered high
quality.
6. Shallow monitoring well sampling
FINDING: The Oregon DEQ and Deschutes County installed and sampled a network of nearly
200 shallow monitoring wells between 2000 and 2004 as part of the La Pine National
Demonstration Project. The monitoring well locations were specified by a registered
hydrogeologist and the wells were installed by a licensed well driller in accordance with Oregon
Water Resources Department well construction standards.
The table below entitled "Network monitoring well data" shows the descriptive statistics of the
sample results from three years of sampling a network of 141 wells. These wells were located at
the periphery of the properties on which the field test system was located. These wells provided
information on groundwater flow direction, depth to water table, and ambient groundwater quality
conditions. The wells were screened at or near the water table in order to document conditions in
the shallow aquifer.
The total nitrogen, nitrate and chloride results show that on average, ambient conditions in the
shallow aquifer are already showing the effects of human sewage discharged to groundwater
because total nitrogen and chloride levels are greater than 1.0 mg/L. Chloride can be used as a
tracer for sewage plumes in the environment of south Deschutes County because human sewage
is the predominant source of this element.
The bacteria sample results (fecal coliform and E. coli) show that these bacteria are not present in
the aquifer.

the shallow aquifer immediately below the drainfield. Data show that nitrate and chloride levels
are elevated in these wells, indicating the effects of the onsite system on the aquifer. There are
some bacteria results indicating that some contamination may be occurring; however, these

results were not repeated during subsequent sampling. Total phosphorus results indicate that the
soil removes most of the phosphorus from wastewater.

This dataset was collected in strict compliance with the Oregon DEQ's quality assurance/quality
control protocols and the laboratory analyses were conducted in compliance with the
Environmental Protection Agency's certification requirements for the DEQ lab, including quality
assurance and quality control specifications. Therefore these data are considered high quality.
B. Nitrate Standards
1. Safe Drinking Water Act standard
FINDING: The US Environmental Protection Agency (EPA) has established the Maximum
Contaminant Level for nitrate as nitrogen (N) as 10 mg/L for municipal drinking water supplies.
This level is considered protective to prevent methemoglobinemia (blue baby syndrome) in
susceptible populations. As a point of comparison, the World Health Organization recommends
setting the drinking water standard at 45 mg/L nitrate. While these standards appear to be
different, the two concentrations are actually the same because 45 mg/L nitrate is equivalent to
10 mg/L nitrate as N. These two values (10 and 45) use different units to measure the amount
of nitrogen contained in a water sample.
The Maximum Contaminant Level does not apply to private drinking water wells but the EPA
encourages private well owners to test their wells annually to confirm that their drinking water
supply is safe.
2, Groundwater Quality Protection
FINDING: The Oregon DEQ establishes groundwater quality protection standards in OAR 340-
040 (available at: http://www.deq.state.or.us/wq/onsite/rules.htm). This rule sets the water
quality standard action level for nitrate as N in groundwater at 70% of the drinking water
standard, or 7 mg/L. The proposed rule is designed to maintain compliance with this standard
on average in south Deschutes County.
Local Rule for Onsite Wastewater Treatment Systems in South Deschutes County
Page 12 of 35 - EXHIBIT "B" TO ORDINANCE NO. 2008-012 (7/9/08)
C. Nitrogen Reducing Systems
FINDING: The Oregon DEQ was awarded $5.5 million for the La Pine National Demonstration
Project. One of the main tasks of this project was to field test nitrogen reducing systems.
During the project, the DEQ partnered with Deschutes County to install and monitor 49 onsite
wastewater treatment systems. Nine of these systems were conventional systems that were
installed and monitored on the same schedule as the nitrogen reducing systems. The nitrogen
reducing systems included 14 different designs; each design was replicated in two or three
locations. Each onsite system was installed at a residential site and monitored monthly for a
year and every two months for the following 1.5 to 2 years.
The results from the field test were reported at national, regional and state meetings of onsite
wastewater treatment professionals. The field test demonstrated that nitrogen reducing
systems exist nationally or internationally that protect groundwater while eliminating the need for
the extensive infrastructure associated with centralized sewer systems. The La Pine National
Demonstration Project results indicate that nitrogen reducing systems currently available on the
market nationally range in performance between about 35% to 96% nitrogen reduction. Not all
of the systems performed adequately for nitrogen reduction and the systems that failed were
replaced. The chart on page 15 shows all of the systems participating in the project by their
performance for nitrogen reduction.
The Oregon DEQ used the results of this field test when the statewide onsite wastewater
treatment system rules were amended in 2005 to allow the use of nitrogen reducing at the
residential level under a construction -installation permit. This rule amendment allowed
Deschutes County to issue permits for nitrogen reducing systems rather than requiring that
homeowners obtain a Water Pollution Control Facility permit from the DEQ.
Since the Oregon DEQ amended OAR 340-071 in 2005, four companies have applied and been
approved for use of their product in Oregon. The Oregon DEQ listing process reviews system
performance for basic wastewater treatment capabilities (for example, biochemical oxygen
demand and total suspended solids reduction) but may not include a review for nitrogen
reduction. If nitrogen reduction is included in the review, the standard that systems must meet
is to discharge Tess than 30 nig/L total nitrogen. Deschutes County has reviewed data on the
approved systems and found that three of these companies produce nitrogen reducing systems
and the fourth does not. A fifth company with a product that is a nitrogen reducing add-on
component was approved for use in Oregon on February 12, 2007; however, this product has
limited availability because the distribution network has not been fully established in Oregon and
certification of installers and maintenance providers has not been completed. While additional
wastewater treatment systems have applied for listing in Oregon, until the DEQ completes
review of the current applications, staff does not know whether additional nitrogen reducing
systems will be available for use locally.
A non-proprietary system is also now available for installation under a construction -installation
permit from the County as a result of the 2005 DEQ rule amendment. Recirculating gravel
filters are available for use and data published by the National Small Flows Clearinghouse
indicates that these systems provide approximately 50% reduction in total nitrogen on a reliable
basis. Other research indicates the performance of these systems may achieve higher levels of
reduction. Data supporting this research is currently under review.

IV. POTENTIAL GROUNDWATER PROTECTION APPROACHES:
A. Sewer Systems
FINDING: The creation of new or the expansion of existing sewers is governed by state rule
(OAR 660-011-0060 available online at: http://www.oreqon.qov/LCD/adminrules.shtml). This
rule defines any wastewater treatment system that serves two or more lots as a sewer system.
Two processes for creating or expanding sewers in rural areas could apply to the south
Deschutes County region and include OAR 660-011-0060(4), when the DEQ determines that a
public health hazard exists and that there is no practicable alternative to sewer (the problem
cannot be solved using onsite systems), and OAR 660-011-0060(9), when there is an imminent
health hazard for which there is no practicable alternative to sewer.
The County retained KCM, Inc. (now KCM-TetraTech, Inc.) to study the feasibility of extending
or creating new sewers in the region. The estimates developed in 1997 assumed that sewer
treatment plant sites could be acquired for $3,000 per acre and that the cost of financing the
treatment works and transmission system would be 3% per year over 20 years. The consultant
estimated in 1997 that each lot would be charged between $19,000 and $28,000 for a sewer
system hook-up.
Since 1997, land, material, and energy costs have increased significantly and would add to the
per lot estimated cost. Adjusting the 1997 costs using historic inflation rates between 1998 and
2008, the per household cost for sewer would be between $24,000 and $33,000. In
comparison, the City of Bend currently charges about $28,000 to hook up to the existing sewer
system plus about $22 per month for service charge. The City of Tualatin charges $40,000 to
hook up to sewer. Oregon Water Wonderland Unit 2 charges about $9,500 to hook up to the
sewer system and $42 per month for service. This low charge reflects the low price for the
sewer treatment plant site (about $500 per acre) and other financial assistance.
The creation or extension of sewer systems requires a large initial capital investment to
construct or upgrade the treatment site and install transmission facilities. Construction grants
are no longer available for creating or extending sewer systems. Construction loan programs
are in place with varying fund amounts available with repayment periods ranging from 5 to 20
years. Using the $19,000-$28,000 estimate above, the annual cost to a sewer system user for
a loan of this amount at 3% would be between $1,275 and $1,880 per household per year.
The amount of time required to establish extensions to existing sewers can be quite long. The
expansion of the existing Oregon Water Wonderland Unit 2 sewer took seven years from the
time the decision was made to proceed until the first new house was hooked to the system.
According to Oregon Department of Land Conservation and Development records, no new
sewers in rural areas have been constructed in Oregon (White, personal communication).
B. Onsite Wastewater Treatment Systems
FINDING: In response to the KCM study referenced above, public participation during the
Regional Problem Solving Project identified the creation or extension of sewers into the rural
areas as the least desired solution because of the cost. At that time, the public directed the
County to pursue the use of innovative kinds of onsite wastewater treatment systems to protect
groundwater quality. In response to this direction from the public, the Oregon DEQ sought and
obtained $5.5 million from the US Environmental Protection Agency to identify onsite
Local Rule for Onsite Wastewater Treatment Systems in South Deschutes County
Page 14 of 35 — EXHIBIT "B" TO ORDINANCE NO. 2008-012 (7/9/08)
wastewater treatment systems that would solve the groundwater pollution problem.
Performance testing of onsite wastewater treatment systems shows they can be as effective as
sewer systems for protecting water quality while maintaining natural groundwater recharge
patterns.
The La Pine National Demonstration Project found that there are several commercially available
systems that will reduce nitrogen at levels greater than achievable using conventional onsite
systems like standard, pressure or sand filter systems. The figure below shows how the
systems participating in the La Pine Project can be ranked by nitrogen reduction. Of the
systems participating in the project, the AX -20, Puraflo, and NITREX systems have applied for
and been listed in Oregon for use under County -issued construction -installation permits. The
County has listed the AX -20 as a nitrogen reducing system and has received data on the
NITREX to be added to the list. The County has not yet received data on the Puraflo system's
nitrogen reducing capability.

The onsite wastewater treatment systems currently available that reduce nitrogen range
between about $9,000 (standard drainfield) and $16,000 (bottomless sand filter) for upgrades to
existing systems depending on the condition of the existing system. Increased costs can be
incurred during upgrades if the existing septic tank is damaged or otherwise unsound or if the
drainfield is failing or inappropriately located. Maintenance costs range between $25 and $35
per month depending on the system chosen by the property owner. Operation costs will vary
depending on the type of system chosen and are largely dependent on electricity demand. In
comparison, a new standard system currently costs between $3,500 and $4,500 and a new
sand filter costs between $10,000 and $12,000. The added cost for the nitrogen reducing
system is between $4,500 and $5,500 for a site using a standard drainfield and between $4,000
and $6,000 for a site using a bottomless sand filter.
Local Rule for Onsite Wastewater Treatment Systems in South Deschutes County
Page 15 of 35 — EXHIBIT "B" TO ORDINANCE NO. 2008-012 (7/9/08)
Some advantages of using onsite system upgrades are that groundwater protection can begin
immediately as compared to typical sewer hookup strategies of waiting until the treatment plant
or collection system is complete before water quality protection becomes effective. The figure
below shows the increasing nitrogen Toad to groundwater historically and into the future as the
area is built out under different scenarios. The capacity to reduce nitrate loading immediately
can be an important consideration because every new system installed in south Deschutes
County that does not reduce nitrogen increases pollutant loading while simultaneously
increasing the demand for financial assistance.

Historical nitrate loading from onsite wastewater systems and eight nitrate loading scenarios
tested with the study -area model. (Morgan et al, 2007)
C. Do Nothing
FINDING: On January 4, 2008, the Oregon Department of Environmental Quality (DEQ) issued
a letter determining that a public health hazard is being created in the region by continued use
of conventional onsite wastewater treatment systems. The DEQ states that potential solutions
to this health hazard may include a variety of approaches ranging from onsite wastewater
treatment systems to expanded or new sewer systems. In comments to the Board of County
Commissioners (Board) on January 30, 2008, the DEQ also indicated that doing nothing is not
an appropriate course of action in light of the developing public health hazard. The proposed
rule is an opportunity for the Board to decide on whether it is appropriate to undertake protective
action at the local level.
Environmental impacts of a "Do Nothing" scenario include Targe areas of the region's
groundwater contaminated with nitrate concentrations greater than 10 mg/L nitrate as N
(equivalent to 45 mg/L nitrate) and adverse impacts to surface water bodies in the region.
Surface water impacts include increased algae growth, fluctuations in dissolved oxygen levels,
and die -offs of aquatic organisms requiring cold, highly oxygenated water. (Morgan et, 2007;
Hinkle et al, 2007)
Financial impacts of a "Do Nothing" scenario are difficult to determine because, while the costs
of sewers or onsite system upgrades are avoided, there are other market impacts resulting from
declining property values because of groundwater quality degradation, impacts to the sport
fishing or recreational boating industry, or the possible imposition of a moratorium on building it
the region.

Page 16 of 35 — EXHIBIT "B" TO ORDINANCE NO. 2008-012 (7/9/08)
V. PROPOSED LOCAL RULE:
FINDING: The proposed amendment would require the use of nitrogen reducing systems in
south Deschutes County for systems permitted by Deschutes County Community Development
Department. While sewer may be a viable option in some circumstances, the county role is
largely that of reviewer for the land use process for creating or extending sewers in rural areas
under Goal 11 (OAR 660-011-0060, Sewer Service to Rural Lands). The county typically does
not have permit authority over sewer systems because the county can issue permits only for
wastewater treatment systems that discharge less than 2,500 gallons per day of residential
strength wastewater.
Staff finds that there may be a variety of approaches that can be used to protect groundwater
quality in south Deschutes County and that one of those approaches is to use nitrogen reducing
onsite systems that are appropriately located and installed. Another approach that may be
feasible is to use community or regional sewer systems or some other approach that provides
the same level of protection. All of these methods are potential actions and therefore need to
be reviewed and permitted by the appropriate authorities to ensure that groundwater protection
is achieved. With this proposed amendment to Deschutes County Code, the County proposes
to ensure that groundwater protection efforts undertaken at the local level meet the overall
groundwater protection goals.
A. Siting criteria for New Development.
The proposed Local Rule will allow onsite wastewater treatment systems serving
New Development to be sited on Tots that are shown to provide 24 inches of natural
vertical separation between the bottom of the trench and the highest level reached
by groundwater.
FINDING: The County, in keeping with direction received during the public process conducted
during the Regional Problem Solving Project, proposes to codify its current practice of allowing
installation of onsite wastewater treatment systems when there is at least 24 inches vertical
separation. Based on this pattern of practice, Tots or parcels with Tess than 24 inches of
separation will not be approved for onsite systems. The County further proposes to deny lots or
parcels that have been filled or dewatered for reasons described below.
Research conducted during the La Pine National Demonstration Project showed that one foot of
soil below the bottom of the trench provided significant protection for the groundwater from
contamination by pathogenic organisms. The table below shows data from samples taken from
the unsaturated zone one foot below the trench in a pressure distribution system. The geometric
mean and median values represent a 99.9% reduction in bacteria counts from the bacteria levels
discharged from the septic tank. The additional foot of soil (for a total of 24 inches) provides
added reduction, particularly for those events when higher bacterial counts are seen, when
groundwater mounding occurs and/or during times of high water use in the house (more
wastewater loaded to the drainfield or sand filter). This data shows how the soil performs an
important treatment function by protecting groundwater from bacterial contamination. These
findings are also corroborated by the findings of the USGS report, "Organic Wastewater
Compounds, Pharmaceuticals, and Coliphage in Ground Water Receiving Discharge from Onsite
Wastewater Treatment Systems near La Pine, Oregon: Occurrence and Implications fo
Transport." (Hinkle et al, 2005; available online at: http://pubs.usgs.aov/sir/2005/5055/index.html

The maximum counts reported here were not replicated with subsequent sampling.
Further, preliminary research conducted on the performance of soil in reducing emerging
contaminants like pharmaceuticals, personal care products and household contaminants indicates
that the natural soil environment provides important treatment for many of these contaminants.
(Tchobanoglous & Leverenz, personal communication).
Groundwater interceptors are a method used to lower, or dewater, the groundwater level within a
specific area. These work by collecting groundwater and diverting it to the nearest surface water
drainage. While these systems may work physically, they tend to have adverse impacts on
surface water quality by diverting nutrient rich groundwater directly to rivers. The rivers in the
Deschutes River watershed are nitrogen limited. This means that diverting nitrate -rich
groundwater to surface water bodies can increase algae and aquatic plant growth, which in turn
affects the levels of dissolved oxygen available for other aquatic organisms, including fish.
Finally, developing high groundwater table lots will add nitrogen loading that can increase the
nitrogen reduction requirements for existing and other future development in the area. Increased
nitrogen reduction standards could translate into higher treatment costs for property owners based
on a preliminary evaluation using the Nitrate Loading Management Model.
B. Future Development on Tots or parcels with high groundwater levels
FINDING: The County, funded by a grant from Oregon DLCD, will begin a public involvement
process to determine whether or how development should be allowed on properties with Tess
than 24 inches of separation from ground surface to the highest level reached by groundwater.
The County, in a work plan approved by Oregon DLCD, began this process during Fiscal Year
07-08. The process will bring together regional stakeholders, including natural resource
managers (Oregon DEQ, Oregon Department of Fish and Wildlife, Oregon Department of State
Lands, etc.) and property owners, to investigate the cumulative impacts of increasing
development in areas with high groundwater levels. Possible outcomes of this work program
could, for example, be increased performance standards for existing systems, increased
protection for wetland and riparian resources and/or maintain the existing pattern of practice.
Any changes to Deschutes County Code would require a legislative process to solicit pubic
comment and feedback on the proposal.
Staff proposes to reference this work program in the code language in the form of a sunset
clause for siting critieria. Standards contained in this portion of the rule would no longer be
enforceable as Deschutes County Code three years from the effective date of rule adoption
unless amended as a result of the high groundwater work program.

process to determine whether or how development should be allowed on properties with Tess
than 24 inches of separation from ground surface to the highest level reached by groundwater.
The County, in a work plan approved by Oregon DLCD, began this process during Fiscal Year

managers (Oregon DEQ, Oregon Department of Fish and Wildlife, Oregon Department of State
Lands, etc.) and property owners, to investigate the cumulative impacts of increasing

Page 18 of 35 — EXHIBIT "B" TO ORDINANCE NO. 2008-012 (7/9/08)
C. Limit the use of easements.
FINDING: The County proposes to eliminate the use of easements to establish a location for a
portion or all of the onsite wastewater treatment system on a lot or parcel separate from the lot or
parcel where the source of wastewater is located. The County has witnessed the dissolution of
easements to the detriment of the lot where the wastewater is generated. In addition, lots or
parcels that propose to use easements typically cannot maintain 24 inches of separation from the
bottom of the trench to groundwater. Developing these Tots can impact wetlands and riparian
resources and is directly counter to the direction received from the public process of the Regional
Problem Solving Project. Further, developing high groundwater lots will add nitrogen loading that
could have the effect of increasing the nitrogen reduction requirements of, and potentially the cost
to, existing development in the area based on a preliminary evaluation using the Nitrate Loading
Management Model.
D. Groundwater level determinations.
FINDING: The County, at DEQ's suggestion, is proposing to codify existing practices used to
determine groundwater levels. This procedure is only used for those sites where soil
characteristics make it difficult to determine the highest level that groundwater reaches. This
procedure only applies to vacant sites seeking approval for development.
E. Performance standards.
FINDING: The US Geological Survey and Deschutes County, in a grant from the National
Decentralized Water Resources Capacity Development Project, developed the Nitrate Loading
Management Model. The development of this model is documented in Morgan et al, 2005 and
Morgan et al, 2007 (available on the web at: http://pubs.usgs.gov/sir/2OO7/5237/).
Performance standards are established by setting constraints for the region, such as:
1. Future Development installs the maximum nitrogen reducing system available (as
defined in the proposed code). This approach reduces the level of nitrogen reduction
required for existing systems in many management areas.
2. Existing Development upgrades to achieve a minimum 35% reduction
3. Shallow groundwater meets the 7 mg/L groundwater quality protection standard on
average.
Additional constraints may be set for the region using this model, including a constraint on the
amount of nitrogen reaching the rivers. No river protection constraints are proposed because it
appears that significant protection for the rivers is provided by reducing nitrogen discharges
from onsite systems. Future river protection projects may be considered to improve riparian
conditions to reduce nitrogen before it reaches the stream channel. If future resource
evaluation work indicates the need for increased performance standards for existing onsite
wastewater treatment systems, staff expects that it would not be necessary to further upgrade
the systems that have already been changed to nitrogen reducing systems in accordance with
the code in effect at the time.
F. Compliance date: Fourteen years from the effective date of the proposed rule.
FINDING: The groundwater studies and predictive models show that groundwater protectior
actions should be implemented as soon as possible. The chart inserted below is taken from the
Local Rule for Onsite Wastewater Treatment Systems in South Deschutes County
Page 19 of 35 — EXHIBIT "B" TO ORDINANCE NO. 2008-012 (7/9/08)
USGS Fact Sheet (Williams et al, 2007) and shows that the cumulative nitrate load already
discharged to the aquifer from existing development significantly exceeds the load needed to
exceed the Oregon groundwater quality action level and the federal safe drinking water
standard. In spite of the science that indicates a need for immediate action, staff has proposed
a fourteen year upgrade schedule to coordinate with projected build -out of south Deschutes
County, the sale of land in and platting of the Newberry Neighborhood, and the long term
average rate of home sales in the region. Fourteen years from 2008 should allow enough time
for the region to build out based on projections for south Deschutes County. Fourteen years
also allows significant financial assistance to be generated in the form of revenue from land
sales in the Neighborhood Planning Area in La Pine or some form of bonding. Finally,
practically speaking, the projected inspection workload for the County's Environmental Health
Division would average 400 to 500 systems per year.

G. Listing nitrogen reducing systems.
FINDING: The Oregon DEQ must first approve any system before the County may issue a
construction -installation permit (OAR 340-071-0135 and -0345). During the listing process, the
DEQ reviews performance data and the National Sanitation Foundation (NSF) certification. The
only explicit nitrogen standard contained in Oregon DEQ rule is a listing criteria for an
Alternative Treatment Technology under Treatment Standard 2 (30 mg/L total nitrogen).
Because groundwater protection goals in south Deschutes County require nitrogen reduction
levels greater than that achieved by a system discharging 30 mg/L total nitrogen in the effluent,
the Oregon DEQ and Deschutes County agree that the County should require additional
information from system manufacturers or designers in order to determine which listed
Alternative Treatment Technologies can support the groundwater quality goals. And, because
the NSF certification process commonly uses influent wastewater that is lower strength (is more
dilute) than typical single-family residential wastewater, the Oregon DEQ and the County agree
that a system's nitrogen reduction capabilities should be defined by field tests of the treatment
system.
H. Other approaches to groundwater protection.
FINDING: The proposed rule is focused on performance standards for onsite systems within
the jurisdiction of Deschutes County and therefore does not limit the creation or expansion of
sewer systems. The creation or expansion of sewers is governed by rules contained in OAR
Local Rule for Onsite Wastewater Treatment Systems in South Deschutes County
Page 20 of 35 - EXHIBIT "B" TO ORDINANCE NO. 2008-012 (7/9/08)
660-011-0060, Sewer Service to Rural Lands. The proposed code language has been modified
to acknowledge this existing process and ensure that the proposed rule does not inadvertently
eliminate sewers as an option.
Other approaches may also become available in the future that cannot be predicted at this time.
The proposed code language has been modified to ensure that these approaches are not
eliminated inadvertently as options and to create a mechanism by which these approaches can
be incorporated into the program to protect groundwater quality.
I. Variances and Appeals.
FINDING: The County received several comments on the Local Rule concepts that concerned
the opportunity to apply for variances or appeals of decisions make under the proposed rule.
The draft rule language includes variances in the case of economic or personal hardship or
where sewer systems are being established.
J. Fees.
FINDING: The Community Development Department is currently entirely fee supported. Other
means of offsetting the cost for permit fees have not been identified or proposed. Currently
retrofits of existing systems would be conducted under a repair permit. Repair permits are
currently $380 plus a $60 DEQ surcharge. The DEQ increased the surcharge from $40
effective July 1, 2008.
K. Violations.
FINDING: The County currently enforces the Deschutes County Code. The proposed rule
would be enforced in the same manner as any other code requirement and the existing County
code enforcement policies are expected to continue to apply for the foreseeable future.
Currently the county works with violators to achieve compliance in advance of going to court. In
the long run, the level of enforcement undertaken will be a decision for Board of County
Commissioners in 14 years. However, the Board will have a responsibility to honor the financial
commitment made by those who have complied, by not waiving the requirements of those who
have not.
VI. FINANCIAL ASSISTANCE:
A. Existing Financial Assistance Programs
FINDING: There are existing mechanisms by which property owners can gain access to funds
available for home improvements, including onsite system repairs or upgrades. The County
proposes to coordinate with existing programs to the greatest extent possible.
1. Pollution Reduction Credit Rebates
FINDING: Developers in the Neighborhood Planning Area have the option of generating
Pollution Reduction Credits or paying into the County's Partnership a fee in lieu of credits. The
fee paid in lieu of generating Pollution Reduction Credits is $7,500 per credit. Currently, Elk
Horn Land Development is offering a rebate to homeowners upgrading to nitrogen reducing
systems in exchange for the Pollution Reduction Credit created by the upgrade.

Page 21 of 35 — EXHIBIT "B" TO ORDINANCE NO. 2008-012 (7/9/08)
2. USDA Rural Development Program
FINDING: The USDA offers loans and grants to low income and elderly residents for home
improvements. Onsite wastewater treatment system replacements or upgrades qualify for these
funds.
3. Neighborlmpact
FINDING: Neighborlmpact currently offers loans to residents at or below 80% of the county
median income bracket for home improvements. Homeowners must repay the loan once the
house is rented, sold or refinanced. As loans are repaid, proceeds are returned to the program
to provide loans for future homeowners. Projects include but are not limited to wastewater
treatment systems, roofs, heating systems, handicap accessibility, and exterior paint.
Neighborlmpact is partnering with Deschutes County during the current round of applications for
Community Development Block Grants with the goal of increasing the availability of funds for
Deschutes County residents.
B. Planned Financial Assistance Programs
FINDING: The Deschutes County Board of Commissioners has established an advisory
committee to produce recommendations on how financial resources should be allocated to
property owners faced with implementing groundwater protection measures. The following
sections provide an outline of the type of financial programs that could help homeowners offset
the cost of groundwater protection measures.
1. Low interest loans
FINDING: Funds generated by payment of fees for credits or from the sale of land in the
Newberry Neighborhood will be used to assist with groundwater protection measures. The
balance between using this fund for loans versus grants may be the subject of a
recommendation from the Financial Assistance Advisory Committee.
Funds earmarked for homeowner assistance from the La Pine National Demonstration Project
must be used for loans, which may include deferred payment loans, as specified by the grant
agreement.
2. Partnership Fund
FINDING: Developers in the Neighborhood Planning Area have the option of generating
Pollution Reduction Credits or paying into the County's Partnership a fee in lieu of credits. The
fee paid in lieu of generating Pollution Reduction Credits is $7,500 per credit. Any funds paid
into this fund are dedicated to assisting homeowners upgrading their onsite systems to nitrogen
reducing systems. The administration of this program will most likely be through a third party.
Funds may be disbursed either as conventional loans, payment deferred loans (liens), and/or
grants. A recommendation for how funds are disbursed may come from the Financial
Assistance Advisory Committee.

Page 22 of 35 — EXHIBIT "B" TO ORDINANCE NO. 2008-012 (7/9/08)
3. State Clean Water Revolving Loan Funds
FINDING: Oregon DEQ administers the program for the state revolving loan fund. Loans to
communities are available for loan periods of between 5 and 20 years at about 2% interest plus
an annual fee of 0.5% of the amount owed. This is a potential source of funds to help
homeowners upgrade their systems or for neighborhoods to extend or create sewers (more
information is available online at: http://www.deq.state.or.us/wq/loans/Ioans.htm). Careful
consideration of the impacts of the cost of administering such funds on the interest rate and fees
is important. Staff proposes reviewing the potential for using this source of funds if the
proposed rule is adopted and after implementation of the County generated financial programs.
C. Source of Funds
FINDING: The County has existing assets of about $350,000 in funds for a low interest loan
program, the revenue from the Partnership Fund, and revenue from the sale of county -owned
land in the Newberry Neighborhood in La Pine. Estimates of the land value are based on 300
acres sold at $100,000 per acre for a total of $30 million. The funds can be made available over
time through the sale of property and the use of the Pollution Reduction Credit Program through
and/or through County bond sales or the loaned use of County interdepartmental fund transfers.
The estimated total cost of retrofits in south Deschutes County ranges between $43 million and
$65 million. Therefore, considerable financial assistance can be generated by using existing
County assets. Using County assets in addition to other programs like the state revolving loan
fund and partnering with organizations like USDA Rural Development and Neighborlmpact
could cover the majority of the projected need for financial assistance.
VII. RECOMMENDATION:
Staff recommends Adoption of the proposed Local Rule in coordination with the
development of additional financial assistance programs that target pollution reduction
actions.

Appendix C: Ordinance 2008-019
REVIEWED
LEGA COUNSEL
For Recording Stamp Only
BEFORE THE BOARD OF COUNTY COMMISSIONERS OF DESCHUTES COUNTY, OREGON
An Ordinance to Establish County Procedures
Under Oregon Rule to Minimize Groundwater
Pollution in South Deschutes County, and
Declaring an Emergency.
ORDINANCE NO. 2008-019
WHEREAS, extensive monitoring and study by the United States Geological Survey ("USGS") and the
Oregon Department of Environmental Quality has shown that the groundwater underlying the south Deschutes
County region is threatened by discharges from conventional onsite wastewater treatment systems serving
development in the region, and
WHEREAS, south Deschutes County is identified as those unincorporated portions of Deschutes
