1 Woodinville BOD Surveillance Investigation and Winery/Brewery Project Protecting people, the environment, and the economy since 1969

2 About King County s Wastewater Treatment System 1.5 million people over 415 square miles About 200 million gallons of wastewater treated every day Three regional and two local treatment plants 350 miles of pipes 34 local sewage agencies About 650 businesses approved to send industrial wastewater into the sewer

3 Working with many types of industries Metal finishing / Electroplating Pharmaceutical manufacturers Can makers Iron manufacturing Centralized waste treatment Food processors Contaminated stormwater Construction dewatering

4 The services we provide Issue approvals to send treated industrial wastewater to the sewer Inspect and monitor the quality of the wastewater coming from businesses Provide assistance and incentives to businesses Enforce regulations, federal and local limits Research new trends and investigate problems

7 How does Brightwater compare to our other treatment plants? West Point South Brightwater Population Served (estimated) 670, , ,000 Area Served 113 square miles 240 square miles 69 square miles Average wet-weather flow (non-storm): 133 mgd 115 mgd 30 mgd ( )

8 Treatment Plant Processes Membrane bioreactor treatment technology Biosolids production via anaerobic digestion State-of-the-art odor control system Reclaimed water availability

9 Operational Issues discovered during first years online Treatment plant staff noticed filterability issues with the mixed liquor from the bioreactor that was resulting in a clogging of the membrane filters. This required frequent backwashing to clear the membranes to maintain adequate flow. Treatment plant staff hired a consulting engineer to determine potential causes. BOD/COD potentially leading to issues of biomass growth

10 The Big Question Treatment plant staff asked the industrial waste staff to determine if the wastewater from industrial users in the service area may be contributing to the filterability issues.

11 Changes in Brightwater Service Area Brightwater designed using engineering report developed in During 6 years of construction many changes in service area including a blossoming winery and brewery tourism industry. In 2004 there were approximately 20 wineries in the Woodinville area. By 2014 there were over 108 wineries and tasting rooms. (Woodinville Wine Country trade association)

19 Figure 13: Typical winery wastes and their sources from your Winery Wastewater Management & Recycling Operational Guidelines

20 Study Design Questions How can we determine the number of wineries/breweries in our service area? Where to go, BMPs, permits? If we permit what is the cutoff point and how to measure? How to determine impacts from loading? Project quickly became more than addressing operational issues with Brightwater.

21 Two part approach Woodinville BOD surveillance investigation - Collect flow data and flow proportioned samples of pollutants of concern to calculate loadings from areas containing high concentrations of Wineries and breweries. Winery survey project Inventory wineries and breweries in service area and develop industry specific BMPs and Permitting guidelines.

22 Surveillance Investigation

23 Study Design Roles and Responsibilities Project Lead (Engineer) - responsible for selecting sites, selecting analytes, contacting partners (lab, flow monitoring group, local sewer agency), receives stores and processes data Project Plan Field Lead Develops sampling plan, selects equipment, coordinates with sampling team, responsible for site safety. Sampling Team execute sampling plan and report issues to Project Lead.

24 King County Environmental Lab Analyze samples and report results Flow Monitoring Group Install and calibrate FlowSharks (Area Velocity Flow Meters) and troubleshoot malfunctioning equipment. Local Sewer Agencies - Coordinate FlowShark installation in non-king County manholes and to provide valuable information regarding the condition of infrastructure. Partners

25 Study Design Site Selection Attempt to isolate flows from North Woodinville and South Woodinville service area to determine loading from small wineries 5 sites chosen 3 King County Manholes and 2 private laterals. King County Manholes Chosen to determine loadings from Redmond/Lake Sammamish entering system and isolate flows from North and South Woodinville Private laterals from Ste. Michelle and Redhook which currently permitted by our program. By sampling these we can subtract their loadings from the total to determine the impact of the smaller facilities.

26 Estimation of Woodinville South Service Area Without Redhook & Ste. Michelle: = A (A31531+A01305+A01306)

27 Estimation of Woodinville North Service Area: = A31511 A01304

28 7 sample events scheduled over the course of 1 year concentrated during late summer and fall to catch the busy production period November 2013 January 2014 April 2014 July 2014 August 2014 September 2014 October 2014

29 Analytes Biochemical Oxygen Demand Total Suspended Solids Continuous ph Chemical Oxygen Demand Dissolved Chemical Oxygen Demand Alkalinity

30 ADS FlowSharks for monitoring flow and pacing samplers Isco 3700 s for collecting samples Custom made interface cables to communicate between ADS flow sharks and ISCO samplers Laptop and flow link software to download and save sampling reports Major Equipment

31 What could possibly go wrong? Equipment Failures- batteries, samplers, flow sharks Rag-Up Cold weather/rain Stormwater at Ste. Michelle Redhook lateral probe placement New Laptop- will not communicate with 3700 s Figuring out what cables go through the manhole ring

32 Solutions Upgrade to Isco 6700 s gave us cont. ph option, but experienced issues with bottle full detectors. Weights on sample line in Redhook lateral to keep probe in place Deflectors/probes for rag-up and tethering the sample line to the handle to prevent pulling Detailed check of weather before sampling to account for changes in sampler pacing due to rain Write service dates on batteries only use newest for project Testing equipment and calibrating before using in the field and keeping the same equipment in the rotation for each sampling event.

37 Wrap up surveillance monitoring Operational Issues with Brightwater are believed to have been caused by internal factors We decided to finish study. We were still interested in loadings from small wineries. ph results indicate buffering occurs when mixed with domestic sewage. Sampling complete

38 Questions Regarding the Surveillance Monitoring Project?

39 Winery/Brewery Project

40 Objectives Development of permitting guidelines specific to industrial and commercial wine & beer making businesses located in our service area. The guidelines will outline recommended best management practices to be implemented at these businesses. Establish minimum production and/or discharge volume based permitting threshold for individual permits

41 Tasks Develop and send IU survey form specific to the winery and Brewery industries Create Breweries and Wineries master lists summarizing company production information learned from surveys Using the list of facilities that volunteered to assist us, visit selected wineries / breweries to learn more about the industries

42 Tasks cont. Write a summary of our findings and develop draft permitting guidelines & BMP s for industries Solicit comments regarding the draft permitting guidelines & BMP s with industry representatives (focus group of volunteers), all affected known facilities & WA State Wine Commission equivalent Beer Commission (if applicable) & Woodinville Wine Association, LSA s, Ecology Draft Proposed permitting guidelines & BMP s

43 Tasks Cont. Public Comment Period Update IW Procedures manual Update KCIW web site & communicate final policy / BMP s to industry representative Send Copy of Final guidelines / BMP s to all affected parties Implementation of Permitting policy

44 Winery Survey

45 Results from Winery Survey Winery Survey- 150 surveys sent out 111 surveys returned 2 undeliverable 37 non reply Second Round - 56 surveys sent out facilities that didn t return survey were mailed a second survey and reminder letter. Surveys were mailed to new facilities not in business during the initial effort 29 businesses willing to participate in development of BMPs and permitting guidelines.

46 Brewery Survey

47 Results from Brewery Survey Brewery Survey 67 Surveys sent out 40 surveys returned 7 undeliverable 20 non reply Second Round 21 surveys sent out 13 businesses willing to participate in development of BMPs and permitting guidelines.

48 Common Themes Most facilities were small and produced very little wine/beer compared to the few large facilities Solids were handled properly and disposed of by composting/solid waste. Lack of ph adjustment at almost all of the small facilities.

49 ph from cluster of small wineries Concern due to lack of ph adjustment at small wineries. YSI Sonde deployed downstream of complex housing numerous small wineries. ph measured over the course of one week.

53 What was learned wineries Seasonality (crush) concentrated during fall ph issues determined through investigation and survey. Will definitely be addressed though BMPs Lees are hard to dispose of as solid wasted due to high water content. Most facilities dumping down drain. Many small wineries but the smallest 81 wineries make up only 9% of the production. Production in Gallons from October 2013 to October 2014 MARK RYAN WINERY DELILLE CELLARS NOVELTY HILL WINERY STRUCTURE CELLARS GUARDIAN CELLARS CHATEAU STE. MICHELLE 81 remaining wineries

54 What was learned breweries Production in barrels from October 2013 to October 2014 REDHOOK ALE BREWERY GEORGETOWN BREWING CO. ELYSIAN BREWING COMPANY MAC & JACKS BREWERY INC. FREMONT BREWING COMPANY PIKE BREWING COMPANY HALES ALES MARITIME PACIFIC BREWING COMPANY Remaining 58 Breweries Like the wineries solids are handled properly, but no ph adjustment Small breweries mostly in Seattle (West Point TP) Redhook and Mac & Jacks in Brightwater Service Area Several large breweries make up majority of production

55 Big Picture Based on production values small operations, even cumulatively, are not close to the few larger facilities. Preliminary data review by our Engineer indicates that there is not likely significant BOD loading from the small wineries/breweries in the area ph issues localized and LSA contact indicated that they haven t seen any impacts. Most of system is newer PVC.

56 Moving Forward Continue to work on BMPs and Permitting Strategy. Calculate Loadings from Woodinville Surveillance Monitoring. Return to Vancouver to present final results.
