Brewery Operations Best Management Practices (BMPs) -- King County Industrial Waste (KCIW) works with industries to make sure their wastewater is properly treated and meets requirements. This protects people, the environment, and the economy.

Wastewater from breweries may contain higher concentrations of organic matter than typical household wastewater. Businesses that send concentrated waste to the sewer system pay an extra surcharge fee because it costs more to treat this water.

To help breweries meet requirements and manage costs, King County has developed these BMPs for brewery wastewater. BMPs are activities, procedures, and features designed to minimize pollutants discharged to the sanitary sewer or released to the environment.

Regulatory Guidance for Cannabis Operations, Version 3, April 2016.
Created in partnership by the Interagency Resource for Achieving Cooperation (IRAC) and funded by the Local Hazardous Waste Management Program in King County.

These guidelines provide government agency inspectors and businesses with the contacts and resources necessary to begin developing an understanding of regulations applied to cannabis operations.

Keep in mind that the following guidelines apply to Washington State Licensed Producers, Processors and Retailers who hold valid Marijuana Licenses issued by the Washington State Liquor and Cannabis Board. This guidance will be updated as legislation changes.

These guidelines DO NOT substitute for the State-mandated rules of WAC (Washington Administrative Code) 314-55 nor any future updates within. The guidelines are intended to provide the resources applicable to all businesses. Additional local ordinances and regulations may apply.

KCIW Sampling Procedures for Customers: Free-Floating Polar Fats, Oils, and Grease (FF-FOG)  - This standard operating procedure applies to the field measurement of free-floating polar fats, oils, and grease (FF-FOG) by industrial dischargers.

KCIW technical memorandum on flow-proportioned sampling for permitted facilities - A 2010 KCIW technical memorandum provides guidance on implementing flow-proportioned sampling. As King County industrial wastewater discharge permits come up for renewal or when the program issues new permits, it requires implementation of flow-proportioned sampling, or a demonstration that the facility's current sampling protocol is adequate. This applies only to facilities with permits, not those with discharge authorizations.

The NIOSH Pocket Guide to Chemical Hazards (NPG) is intended as a source of general industrial hygiene information on several hundred chemicals/classes for workers, employers, and occupational health professionals. The NPG does not contain an analysis of all pertinent data, rather it presents key information and data in abbreviated or tabular form for chemicals or substance groupings (e.g. cyanides, fluorides, manganese compounds) that are found in the work environment. The information found in the NPG should help users recognize and control occupational chemical hazards. The National Institute for Occupational Safety and Health (NIOSH) is the federal agency responsible for conducting research and making recommendations for the prevention of work-related injury and illness.

The King County Stormwater Pollution Prevention Manual provides best management practices (BMP's) for managing stormwater on commercial, multi-family and residential properties. The manual provides detailed information for businesses, residents, managers, and owners of property in unincorporated King County, and describes the actions we are all required to take to reduce the contamination of stormwater, surface water, and groundwater, to comply with Federal Clean Water Act requirements.

Literature Review of Existing Treatment Technologies for Industrial Stormwater, 2011: This report, prepared for the Washington State Department of Ecology by Herrera Environmental Consultants, identifies technologies for treatment of industrial stormwater. The report was originally developed for industrial facilities covered under the Ecology NPDES permits for treatment and discharge of industrial stormwater to the Lower Duwamish Waterway. Although not all of the technologies identified in the report are applicable to the treatment of contaminated industrial stormwater discharged to the King County sewer, KCIW is providing this report as a technical resource to industrial users and their engineering consultants.

The selection of an appropriate treatment technology for a particular discharger can be very site-specific and King County provides no guarantees or endorsements of the products included in this report. Note that use of any technology by an industrial user of the King County sewer system requires prior KCIW approval.

Available upon request: contact KCIW engineer Bruce Tiffany, email: or see staff phone numbers.

KCIW has developed screening levels for certain volatile organic compounds (VOCs). These VOC screening levels are provided as guidance to industrial users of the King County sewer system and are not an authorization to discharge.

Technical assistance organizations

Pacific Northwest Pollution Prevention Resource Center (PPRC) is a non-profit organization that is one of the Northwest's leading sources of pollution prevention (P2) information.

The Department of Ecology is the accrediting institution in Washington State for environmental laboratories , including those that test drinking water. Accreditation of environmental laboratories ensures a lab is capable of providing accurate and defensible analytical data. Many grant-based or legislatively mandated scientific studies require the use of an accredited laboratory.

The Washington State Department of Ecology provides efficiency services for manufacturing and industrial facilities including a technical assistance team made up of engineers and scientists. They use current state assessments and engineering analysis to improve the efficiency of your operations without sacrificing the quality of your products.

The Water Smart Technology Program of the Saving Water Partnership of Seattle and participating local water utilities offers water conservation rebates and technical assistance to eligible commercial, industrial and institutional customers of water providers.
