ATTACHMENT B — DISCLOSURE EXEMPTION AFFIDAVIT

____________________ (Affiant), being first duly sworn under oath, and representing [insert Proposer Name] (hereafter “Proposer”), hereby deposes and swears or affirms under penalty of perjury that:

1. I am an employee of the Proposer, I have knowledge of the Intermediate Procurement referenced herein, and I have full authority from the Proposer to submit this affidavit and accept the responsibilities stated herein.

2. I am aware that the Proposer has submitted a Proposal, dated on or about [insert date] (the “Proposal”), to the State of Oregon (State) in response to Intermediate Procurement [insert Oregon Buys Bid #], for [insert description of Intermediate Procurement], and I am familiar with the contents of the Intermediate Procurement and Proposal.

3. I have read and am familiar with the provisions of Oregon’s Public Records Law, Oregon Revised Statutes (“ORS”) 192.311 through 192.478, and the Uniform Trade Secrets Act as adopted by the State of Oregon, which is set forth in ORS 646.461 through ORS 646.475. I understand that the Proposal is a public record held by a public body and is subject to disclosure under the Oregon Public Records Law unless specifically exempt from disclosure under that law.

4. I have reviewed the information contained in the Proposal. The Proposer believes the information listed in Exhibit A is exempt from public disclosure (collectively, the “Exempt Information”), which is incorporated herein by this reference. It is my opinion that the Exempt Information is exempt from disclosure under Oregon’s Public Records Law under the specifically designated sections as set forth in Exhibit A or constitutes “Trade Secrets” under either the Oregon Public Records Law or the Uniform Trade Secrets Act as adopted in Oregon because that information is either:

A. A formula, plan, pattern, process, tool, mechanism, compound, procedure, production data, or compilation of information that:

i. is not patented,

ii. is known only to certain individuals within the Offeror’s organization and that is used in a business the Offeror conducts,

iii. has actual or potential commercial value, and

iv. gives its user an opportunity to obtain a business advantage over competitors who do not know or use it.

or

B. Information, including a drawing, cost data, customer list, formula, pattern, compilation, program, device, method, technique or process that:

Introduction

Winter Lake floodplain, where the Winter Lake Phase III project is planned, lies west of the City of Coquille, Oregon 0.55 miles (Figures 1 and 2). The “Winter Lake” floodplain area south of North Bank Lane/Hwy 42S, and west of Coquille, OR, at over 1,806 acres, represents one of the largest contiguous land areas in the lower Coquille Basin with high potential for Oregon Coast (OC) coho overwinter habitat and high-quality pasture production. Approximately 1,295 acres within the Beaver Slough Drainage District (BSDD) are below elevation 8.0ft NAVDD 88, and thus below the highest measured tides. The project-area is upstream of saline influence at River Mile (RM) 21.5 in the Coquille estuary (Figure 1). The Beaver Slough Drainage District (BSDD) was formed in 1906-1907 and this collaboration provided the framework for initiating converting the forested tidal floodplain into pasture grazing lands through installation of the linear canals and top-hinged wooden tidegates at the interface with the Coquille River in 1908-1909. Prior to conversion the lands were forested with Oregon ash, red alder, willow, cottonwood, some spruce, and contained a dense tidal channel network (Benner 1992). The Coaledo Drainage District (CDD) was formed thereafter and installation of a tidegate on Beaver Creek in the “Winter Lake” area west of the BSDD allowed for drainage of pastures on the west side of Beaver Creek.

The average high tide elevation in the Coquille River basin is ~7.5ft NAVDD88. Prior to 1908, the Winter Lake floodplain was tidally influenced on all lands in the project area. Daily inflow/outflow of water occurred through highly sinuous, on-grade natural tidal channel networks. Historical drainage has developed highly productive pasture grazing lands, which contribute substantively to the economic productivity of Coos County. Historically native salmonids, specifically coho (Oncorhynchus kisutch) and fall Chinook (O. tshawytscha) juveniles used Winter Lake habitats heavily during fall/winter/spring months to feed and rear prior to smoltification. Perhaps 50% of juvenile coho parr used these locations annually prior to migrating to the ocean. Production of salmon on these landscapes resulted in the historical estimate for coho production in the Coquille Basin having peak abundance of 417, 000 adults, which is greater than all other rivers on the Oregon Coast, other than the Umpqua River Basin and 744% greater than returns since 1958. Reestablishing a collaborative “Working Landscapes” for agriculture and native salmon is presently a priority for the lands in alignment with the Oregon Plan for Salmon and Watersheds.

It is critical to note that the 1908 linear steam shovel installed channel construction traversed across microtopography on the landscape without consideration of swales that can pond water following rainfall or irrigation events. These areas would not have retained water prior to human alteration due to the natural highly dendritic tidal channel networks. Thousands of feet of the historical tidal channels that connected these swales were also filled after 1908. Many of these swales are 0.5-1.5ft in depth and persist once filled, for 2-4 weeks even under dry summer conditions. In spring drainout they present a stranding risk for juvenile overwintering coho. In summer, if filled, they present water that can stagnate without fish present and provide optimal habitat for mosquito larval production. Due to limited economic capacity at the time and through the present, no major excavation effort has occurred to improve hydrologic connectivity in the Winter Lake Phase III project area to properly connect these hydrologically dysfunctional swales.

From 2010 to 2017 the BSDD, Oregon Department of Fish and Wildlife (ODFW), and The Nature Conservancy (TNC), with critical partners including the Coquille Tribe, developed restoration actions for a portion of lands within the BSDD. The plans focused on two projects (Phase I and II) within the management Units of the BSDD (Figure 3). The “Winter Lake Phase I,” project installed seven new tidegates to replace the previously existing undersized and top-hinged gates that had obstructed fish movements.

Four 8.0ft corrugated metal culverts (CMP’s) installed in the early 1990’s were replaced with seven 10.0x8.0ft concrete box culverts at the interface of the BSDD floodplain with the Coquille River. Slide-gate style and side-hinged aluminum tidegates (Figure 4) were installed to provide a dual controllability. The Vertical Slideframe Style Tidegates (VSFTG) network is configured with both manual and remote access control. The new tidegates have the capacity to be operated with Muted Tidal Regulator (MTR) technology, whereby the tidegates can be opened to allow for tidal inflow to a desired set level, computer controlled, and linked to river/tidal level feedback. The new gates have increased the capacity for water movement into and out of the 1,700-acre BSDD by 300% and has provided for greatly enhanced pasture irrigation capability for pasture irrigation into Units 1 and 3.

In 2018, the Unit 2 restoration project or “Winter Lake Phase II” was implemented and a total of 31,000ft of tidal channel were excavated as designed by Tetratech Engineering staff through coordination with ODFW and the BSDD in the 407 acres of Unit 2. The main tidal channel upstream of the C3P tidegates in Unit 2 was designed with capacity that exceeds the four concrete box culverts and tidegates. This has allowed for full ability to serve water from the C3P tidegates to Unit 2 lands and provide juvenile coho and other native fish passage into the site. Team members that had been on the U.S. Fish and Wildlife Service (USFWS) Ni-les’tun mosquito resolution Team in 2012-2015 were critically included in the designs of Phase II. Implementation of Phase II, designs incorporated detailed layout intent on connecting swale locations vulnerable to fish stranding and mosquito production. ODFW monitoring 2019-2023 has documented only limited mosquito production from the lands on a small component (<10 acres) of the 407 acre Unit 2 area (Figure 3).

The proposed “Winter Lake Phase III” project has been developed by a team of partners including Coos Soil and Water Conservation District (Coos SWCD), the ODFW, and the BSDD. The project is designed as both ecological restoration and agricultural improvement to complement the BSDD C3P tidegate replacement project completed in 2017 (Winter Lake Phase I) and the 2018 installation of 31,000 ft of restored natural tidal channels which was completed in Unit 2 (Winter Lake Phase II). The Phase III Project Proposal seeks to address hydrologic connectivity within BSDD Units 1 and 3 (1,700 acres) and two pastures, which are 62 and 44 acres respectively, in the Coaledo Drainage District (CDD) (Figure 3). Full Phase III project details are on file with Coos County Planning Department or available from Coos SWCD, ODFW or the BSDD.

Winter Lake Units 1 and 3 have high inherent potential for much improved agricultural grass growth and native juvenile salmonid fish production; however, their current hydrologic disconnection yields:

a). Restricted capacity for landowning ranchers to manage water inflow/outflow from pastures during spring/summer months due to 1). Insufficiently sized channel networks to expedite drainout; 2). Historical placement of existing networks in locations that do not follow micro-topography, thus preventing spring drainout and ponding of water following irrigation events.

b). Stranding potential due to a low density of channels present across large portions of the floodplain land area to provide refugia for native fishes when floodwaters periodically recede, which results in high potential for mortality, predation, and stranding for salmon due micro-topography hydrologic dysfunctional land areas of Units 1 and 3.

c). Limited and risky access for fish from existing canals into floodplains due to which are rich in macroinvertebrate food items when flooded; resultantly, there is limited potential for fish use of the floodplain for foraging despite having very high production of food items.

d). Mosquito production potential in micro-topography hydrologic dysfunctional land areas of Units 1 and 3.

Winter Lake Phase III specifically proposes to install and reconstruct 97,000ft of tidal channels and replace 42 existing undersized culverts and associated old style top-hinged tidegates with 38 new culverts and higher technology “fish friendly” tidegates. In addition, twenty-two hydrologic bulbs will be installed to increase sediment transport from interior channel network through a forcing of water flow to end points of the reconstructed/new channels. This will greatly reduce or eliminate the need for future excavation/cleaning of the tidal channel networks. The project actions are anticipated to maximize hydrologic connectivity in order to achieve a balance of fish/wildlife and agricultural (pasture) production.

NOTE: Irrigation has been used by ranchers within the BSDD consistently over the past 100+ years through opening of the tidegates and allowing tidal inflow into pastures on high tide cycles. The new C3P tidegates installed in 2017, greatly enhanced irrigation inflow potential at the main tidegate network. Native fish have adapted to both tidal and floodwater inflow regimes.

BSDD irrigation tactics utilize tidal inflow, which is a natural hydrologic pattern within native fish adaptive capacity. Native fish have used inherent adaptive genetic traits to react to tidal/floodwater cues that allow movement into floodplain habitats and retreat to channels following relatively short (6hr tidal cycles) inundation periods. Irrigation is implemented from mid-June to mid- September generally for the individual pastures over one or two days monthly.

Pasture production on the Phase III project area has been negatively affected to a high degree through time, with the inability (largely due to state and federal permitting complexities), to complete water inflow/outflow channel maintenance. Juvenile fish access from the main Coquille River was addressed through the Phase I installation of new culverts and associated higher technology tidegates. Phase I provided greatly increased capacity to expedite drainout during spring months and deliver irrigation water during summer. The increased site potential for fish and pasture grazing accommodated by Phase I actionsPhase I cannot be realized without implementation of Phase III. Phase III is a specifically designed project to address agricultural and fish production goals for the site, while implementing strong measures to reduce mosquito production, which are a residual effect of ditching and draining efforts dating back to 1906-1908. The Phase III Team has incorporated feedback into the designs from professional vector/disease specialists of both the American Mosquito Control Association (AMCA) and Vector Disease Control International (VDCI).

Water on pastures in the summer does not inherently allow for mosquito production. The water must be in a location where it ponds, is not moving, does not drain, and fish are not present. Ponded water that does not drain restricts/inhibits grass growth and is a highly undesirable condition for ranching operations.

The Winter Lake Phase III project:

1) Incorporates on grade channels in order to facilitate positive and full drainout on low tides following delivery by flood flows or irrigation;

2). Has designed channel networks that are greatly expanded in density and extent over the current linear network in order to that penetrate to pasture locations and provide inflow/outflow where water can pool, stagnate, produce mosquitoes and strand fish; and

3). The new channel networks will provide greatly increased access and livable space for fish during winter and summer including mosquitofish, three-spined sticklebacks, which are strong mosquito larva predators of larva in locations where they might be produced.

The Project Team considers inhibiting mosquito production as a strong goal with the Phase III project.

Mosquito abundance during summer already appears to have increased within Coos County in the past decade, based on anecdotal information. As part of Winter Lake Phase III permit review process, the Coos County Planning Department has recommended that mosquito monitoring be implemented for the project area. Mosquito numbers were notedly elevated around near the City of Coquille and valley floor in 2023.

This plan has been developed by ODFW, VDCI, and Coos SWCD staff for the BSDD to address concerns related to mosquito production within the Winter Lake Phase III project area.

Goals and Tactics

1). Establish a Mosquito Monitoring Advisory Team with a strong science based constituency.

2). Determine if mosquito production is occurring on land parcels within the Winter Lake Phase III project area. This includes Units 1 and 3 and two smaller pastures in the CDD (Figure 3) during May through September. Identify the specific locations, as is possible, where larval mosquito production is occurring within the Winter Lake Phase III project area.

3). Assess the general abundance of larval production if noted within the Winter Lake Phase III project area.

4). Assess the general abundance of adult mosquitoes within Units 1, and 3 at selected locations.

5). Establish control sampling locations at a minimum of three County locations at the discretion of the Winter Lake Phase III Team.

6). Obtain mosquito samples from Units 1 and 3 within Winter Lake and submit for species analysis.

7). Based on speciation of mosquitoes captured in Units 1 and 3 within Winter Lake, correlate to the disease transmission potential of species identified (standard literature or vector professional knowledge).

8). Establish potential and treatment methodologies for any mosquito detection that meets thresholds established by a collaborative decision making process of the Winter Lake Phase III Mosquito Monitoring Advisory Team.

Goal 1: Discussion and Recommendations Mosquito monitoring and management is most effective when based on science driven principles that direct the methodologies and implementation. Without effective understanding of how, when, and why habitats produce mosquitoes on a given landscape, monitoring efforts and any potential treatment actions are largely doomed to failure or greatly enervated. Socially based assumptions embedded in perception of origin of mosquitoes that are detected or supposition of habitat capability or lack thereof to produce mosquitoes is likely to lead to weakly effective or non-effective conclusions on the number of mosquitoes being produced, location of production, misaligned treatment tactics/timing/potential for success, and improper thresholds for treatment.

The Winter Lake Phase III Mosquito Monitoring Plan recommendation is for formation of an advisory team that includes: 1). Seven members consisting of:

• A Beaver Slough Drainage District Representative: BSDD is the applicant for the Winter Lake Phase III project and coordinator for the project area landowners.

• An ODFW representative: ODFW staff have extensive experience with mosquito assessment for various habitats within the Coquille River basin. They are also a landowner in the Unit 3 lands of the project, were on the Ni-les’tun USFWS resolution team from 2012-2015.

• A Coos Soil and Water representative: Coos SWCD staff are the project team coordination hub, financial manager, and have previous mosquito monitoring and habitat assessment experience.

• A Coos Health and Wellness Representative: Coos Health and Wellness staff have previous mosquito monitoring experience and represent county health concerns.

• An Oregon State Extension representative: This individual has connectivity to OSU staff that work in agriculture operations. The Phase III project area is predominantly under livestock production use currently.

• A Vector Disease Control representative: from either Jackson County Vector Control or other vector control district within Oregon or representative from private firm that professionally works in mosquito management (e.g. Nikki Harris with VDCI, Ontario, OR).

• A representative from the public at large: This representative much live within the City limits of

Coquille and have a science based bachelor’s degree or equivalent. This representative must not have attended or submitted previous testimony for County Planning Work Session or Hearings associated with the Winter Lake Phase III project.

The Winter Lake Mosquito Monitoring Advisory Team will convene twice annually at a minimum, once in April or May and again in September or October. The core Winter Lake Phase III Team (Coos SWCD, ODFW, BSDD) will coordinate the formation of the Advisory group. BSDD will be responsible to coordinate and convene the two annual meetings. Communications as needed on a daily/weekly basis by email, Zoom/Teams, and phone are anticipated on sampling and results. Advisory group staff will be allowed to accompany any sampling effort of core Winter Lake Team (Coos SWCD, ODFW, BSDD) on the project area or other locations in the County.

Goal 2: Discussion and Recommendations In order to achieve goal number 2, a combination of adult and larval sampling will be incorporated as specified by VDCI staff. Coos SWCD, ODFW, the BSDD, and landowners will carry out monitoring efforts.

Rationale for Integrating Larval and Adult Surveillance:

Integrating mosquito surveillance in an effective manner is a crucial step in managing mosquito populations. Larval surveillance provides insights into the spatial distribution, abundance and breeding habitats of local populations of mosquitoes. However, it comes with limitations. Larval monitoring is limited to property that is accessible. This does not provide a full representation of the mosquito population. Adult mosquito surveillance helps to elucidate the mosquito distribution, density, and species composition throughout the area. Furthermore, it can provide direct evidence of an increased risk of contracting mosquito-borne viruses. It is also crucial for the efficient and precise application of larvicide by detecting areas in which large populations of mosquitoes are emerging. One of the important components of including adult sampling is also the ability to determine the overall density dependent impact potential of the adult mosquitoes for human populations. If larva are detected, the relevance is really related to if the adult numbers are low or at a level for realistic effects to human populations. Several larva that are detected over a small land area where there is standing stagnant fishless water may contribute only moderately to adult numbers, whereas a low density of larva, yet distributed over a large area of wetted habitat area will likely contribute substantially to adult abundance. Combining both allows the opportunity to create an accurate representation of where there is a large population of mosquitoes and where they could possibly be coming from.

Methodologies for Integrated Surveillance:

Larval Surveillance Purpose: The purpose of larval mosquito surveillance is to determine if significant larval breeding sites are currently located on the site that needs to be connected to the tidal inflow/outflow exchange with either machine constructed or in specific locations hand-dug channels.

Collection Procedures: Larval mosquitoes are collected with standard “dipping” procedures. The dipper consists of a white plastic cup, 400ml in volume, with a wooden dowel handle. Dipping for mosquito larvae is used as a survey tool simply to determine the presence or absence of larvae and involves taking several water samples from designated areas and then counting the larvae captured in each dip (VDCI 2024, and O’ Malley 1995)

Dipping on the Winter Lake Phase III Units 1 and 3 would incorporate samples on land areas with remaining standing water after May 15th through September 15th. A visual inspection for water on individual land ownerships would be conducted once monthly in the period. Stagnant disconnected locations unlikely to have fish present would be dipped with data being recorded on hardcopy datasheets and then provided to the Coos SWCD. A minimum sample of 50 dips per land ownership distributed across standing water locations would be completed once monthly. Dipping during July, August, and September should be conducted within 5-9 days following any irrigation events not to exceed the once monthly frequency.

Adult Surveillance Purpose: The purpose of adult mosquito surveillance is to determine if significant numbers of adults are hatching from locations around the trap site are at an abundance to potentially cause an impact on citizens in the area.

Collection Procedures: Adult mosquitoes are collected with a trap. There are multiple types of adult surveillance traps. The most common type and trap that would be the most applicable to the Winter Lake project is the CDC light trap. CDC (Centers for Disease Control) Miniature Light Traps are lightweight, portable, battery operated traps that will be used throughout the mosquito management area to assess local adult mosquito population abundance. These traps are baited with dry ice (a source of CO2) to increase their appeal to host-seeking mosquitoes and are usually sampled weekly throughout the mosquito season.

Adult mosquito trapping will be conducted once monthly similar to dipping methods from May 15th to September 15th annually. A total of one Heavy Duty EVS CO2 trap (as can be obtained from http://www.bioquip.com) per land owner within Units 1 and 3 will be set each month (see Appendix A for full Adult Surveillance Protocol).

Goal 3: Discussion and Recommendations Refer to goal #2 incorporating tactics for larval sampling on individual land ownerships.

Goal 4: Discussion and Recommendations Refer to goal #2 incorporating tactics for adult sampling on individual land ownerships and Appendix A.

Goal 5: Discussion and Recommendations Annual variability dictates that control sampling locations for adult mosquitoes are incorporated with sampling at Winter Lake. An increase in abundance at Winter Lake needs to be evaluated in the context of County wide trend to ascertain if abundance metrics are related to climactic conditions for the sample year or on habitat conditions within Winter Lake. Mosquito habitat conditions vary year to year, however, the trend climactically is indicating that western U.S. habitats have had an increasing trend for production of mosquitoes over the past 20yrs (https://www.climatecentral.org/graphic/mosquito-days- 2023?graphicSet=Local+Mosquito+Days&location=Portland,+OR&lang=en).

Note: It is assumed that as sampling of adult mosquitoes and provision of data at additional non Winter Lake locations serves to meet Coos County goals that Coos County will allow access for the core Winter Lake Team (Coos SWCD, ODFW, and BSDD) to adult mosquito sample on County owned lands (e.g. County parks, County forest).

Goal 6: Discussion and Recommendations Mosquito samples obtained from EVS light traps will be placed in freezer following field capture for a minimum of 10 minutes, mosquitoes will then be emptied from nets, placed in small plastic storage containers, and stored in the freezer until shipment to the laboratory or other Winter Lake Phase III team determined location for species I.D.

Goal 7: Discussion and Recommendations Coos SWCD and ODFW staff will communicate directly with Coos Health and Wellness staff and the Winter Lake Phase III Mosquito Monitoring Advisory Team on the potential for species captured potential to transmit disease.

Goal 8: Discussion and Recommendations http://www.bioquip.com/ https://www.climatecentral.org/graphic/mosquito-days-2023?graphicSet=Local+Mosquito+Days&location=Portland,+OR&lang=en https://www.climatecentral.org/graphic/mosquito-days-2023?graphicSet=Local+Mosquito+Days&location=Portland,+OR&lang=en

Based on Goals 1-6, the Winter Lake Phase III Mosquito Monitoring Advisory Team will advise on if the data indicates that abundance of mosquitoes, location, and tactical capability of the treatment to be effective warrants treatment. The Team will also advise on types of treatment tactics (see Appendix B) that might be incorporated. Deference will be given to the Vector Disease representative by the Team for any final recommendations for treatment and methods.

Conclusions

The Winter Lake Phase III project has been designed with channel layout that will address micro-topography conditions where water currently ponds and fails to drain out on low tide cycles. Those locations are potential habitats where mosquito production can occur. The Phase III Project Team and project landowners recognize that while the project has strong design features to reduce mosquito habitats, monitoring will support understanding of the success of the new 97,000ft of tidal channel, increased culvert capacity, and appropriate invert elevation designs to support hydrology more similar to historically and reduce potential for mosquito production. A short annual report of findings and any actions taken based on investigations will be prepared by (TBD) following each sampling year and submitted to Coos Health and Wellness, Coos County Planning, ODFW, Coos County Commissioners, and the Winter Lake Phase III Mosquito Monitoring Advisory team.

Appendix A Adult Mosquito Surveillance Plan

Appendix A. Adult Mosquito Surveillance Plan (as supplied by Vector Disease Control International)

Standard Light Trapping: As directed in the Winter Lake Phase III Mosquito Monitoring Plan the project proponents or landowners will conduct pre- and post-treatment mosquito population surveillance using CDC type light traps or equivalent. Mosquito trapping shall be performed using standard methodologies for trapping mosquitoes:

• Traps are baited with dry ice (or a similar source of CO2)

• Traps are powered with a 6 volt, rechargeable battery, or 4 D-cell batteries.

• Traps are set in the afternoon and picked up the following morning, allowing for a minimum of 12 hours collection interval.

• Mosquito Collections are transferred to a laboratory (or other suitable location) for sorting, speciation and enumeration.

• All trap locations are GPS-referenced, with latitude and longitude noted on hardcopy datasheets.

• After collections are counted, the number of mosquitoes in each group for each species must be recorded, entered into a database, and mapped for a graphical presentation so that changes in mosquito abundance can be readily examined and verified by the Winter Lake Phase III Mosquito Monitoring Advisory Team.

A minimum of five (5) traps will be used in each designated treatment area and shall be spaced to provide reasonable representation of adult mosquito populations in the treatment area. For larger treatment areas, up to ten (10) traps may be set if necessary. To allow for increased response time, 5 traps per treatment area is preferred and increased trap numbers should only be required when sufficient representation of the spray block cannot be obtained with the minimum number.

Trapping should take place at least 24 hours prior to any larvicide or adult treatment (pre-treatment) and within 48 hours following (post-treatment) each treatment. All pre- and post-application traps are placed in the same location.
