SINCLAIR INLET FINAL REPORT EXECUTIVE SUMMARY Table E1 below describes how this project met its goals, anticipated outcomes, and required deliverables: Table E1. Comparison of Project Results to Project Goals, Outcomes and Deliverables Goals Status Comments Designated beneficial uses will be restored and protected Progress Remaining sources of fecal contamination must be corrected, and flushing of contaminated discharges must occur before we can fully assess project success. Healthy waters prevented from being degraded Progress Beneficial uses were protected by educating 784 watershed residents about preventing sources of nonpoint pollution on their properties. Water bodies on the 303(d) list for fecal coli form bacteria contamination will Progress This project resulted in improvements for four TMDL (4A) streams including Black Jack, Annapolis, Karcher, be restored to water quality standards. and Sacco Creek Status Water Quality & Environmental Outcomes Reduce fecal coliform (FC) levels to standard in project area streams and Progress Good progress has been made on four TMDL streams as shown above. Results were mixed for other major marine waters. streams in the watershed and the receiving marine waters. Reduce FC pollution in shoreline drainages and storm water outfalls. Achieved Inspect 450 onsite sewage systems. Exceeded 784 onsite sewage systems were inspected. Correct 23 failing onsite sewage systems. Exceeded 79 of 84 failing onsite sewage systems have been repaired. Inspect 15 high and medium priority agricultural properties. Exceeded 52 high priority farms were investigated. Nine (9) farms were found to have water quality concerns. Install best management practices at 15 agricultural properties. Exceeded See Kitsap Conservation District report in Appendices for project results. Thirty (30) agricultural properties installed best management practices. Distribute 50 pet waste buckets. Revised by West Sound Distribution of pet waste buckets was cancelled in favor of distribution of West Sound Storm Water Environmental Outreach Outreach Group pet waste brochures and posters to property owners with pet waste problems. Also Mutt Group Mitt information was submitted to interested community groups throughout the project. Implement marina pump out outreach program by distributing 100 educational Revised by WSU Extension WSU Extension recommended revising this task due to the confounding impacts of the economic downturn boat seat cushions and monitoring pump out use before and after distribution. on marina pump-out data Provide public meetings and workshops for a total of 150 participants. Exceeded Provide Washington State University training workshops for an anticipated Achieved Realtor workshops conducted by WSU May 7, 2009, March 1, 2010, and May 6, 2010 thirty realtors. Status Performance Items & Deliverables Project administration/management Achieved All required reports and billings have been submitted. Public education and outreach Exceeded Four (4) public meetings, three (3) onsite sewage system work shops, five Girls Exploring Math & Science workshops, four Girl Scout day camp presentations, two South Kitsap High School workshop, and three (3) KCD public outreach events were conducted during the project period. Pollution Identification and Correction Achieved Completed, 79 of 84 (94%) of failing onsite sewage systems have been repaired Final report Achieved Completed and submitted to Ecology for approval 1 Sinclair Inlet Fecal Pollution Reduction Project Kitsap Public Health District Water Pollution Identification & Correction Program Kitsap Public Health District’s (Kitsap Health) Water Pollution Identification and Correction Program reviewed the results of samples collected, surveyed residents and made observations during the Sinclair Inlet Fecal Pollution Reduction Project. Many of the OSS in the area experience risk factors that can lead to failure including age,lack of permit records, shallow ground water, inadequate setback to surface waters, and deeper installation depths that can degrade the ability of soil bacteria and microbes to provide adequate treatment. OSS without permit records have not been evaluated and inspected for conformance with installation requirements that minimize failure risk including: size and depth of tanks and drainfield, type of materials used, and level drainfield trenches for equal effluent distribution. Shoreline surveys are an effective method of finding OSS failures and other pollution sources. Cost share money for livestock and agricultural animal manure land management practices has been a good catalyst, resulting in behavior change and increased landowner stewardship. This incentive program has proven effective in achieving water quality improvements in challenging situations and
