Home My WebLink AboutEXHIBIT_056Ev eb DEPARTMENT OF ECOLOGY State of Washington l-502 Producer/Processor Wastewater Discharge Checkl ist Washington State's water pollution control law requires a permit for the discharge of industrial or commercial wastewater to "waters of the state", which includes surface and groundwater. Dischargers of wastewater must provide all known available and reasonable methods of treatment (AKART), prevention and control before discharge. The Washington State Department of Ecology (Ecology) regulates discharges of wastewater with permits to ensure AKART is provided and that public health is protected. Checklist Ecology developed this checklist to determine if a process wastewater associated with an l-502 producer/processor will discharge to waters of the state and require a discharge permit. Please submit the completed checklist 60 days in advance of the start of producing/processing operations to allow sufficient time for review. Wastewater Discharge Options Ecology will not require a discharge permit when the completed checklist showS there will be no discharge of a pollutant into waters of the state when the I-502 applicant implements AKART. Wastewater information on this new industry is evolving. [n the majority of cases to date, the volume of wastewater from I-502 producer/processors is considered to be minimal or there is no discharge. Potential discharge options: 1. Publicly Owned Wastewater Treatment Works Discharge to a local municipal sanitary sewer system is the preferred option for I-502 facilities that have discharges associated with cleaning, rinsing, THC extraction, hydroponic irrigation, and the manufacture of edible products. Discharges can be either direct connection to the sewer collection system, or by collecting the I-502 wastewater in a tank and transporting it to the municipal sanitary system for disposal. Written approval must be obtained from the local sewer agency prior to commencing any discharge. It is highly recommended that I-502 facilities considering this option contact the Water Quality Program's pre-treatment engineer at the appropriate regional Ecology office for guidance. 2. Septic Tank and Drain Field/French Drain Ecology does not allow commercial or industrial wastewater to be discharged to a septic tank/drain field or French drain system. Ecology does not accept that septic tanks/French drains provide AKART for commercial and industrial wastewater, unless the discharge meets the requirements of the local health department. Ecology generally considers the presence of floor drains in an I-502 producer/processor facility to be connected to a septic tank/drain field system. 3. Surface Water Discharge Ecology strongly discourages this discharge option. It would require that the operation be permitted under the federal National Pollutant Discharge Elimination System (NPDES) under the authority of the Clean Water Act. The permit would contain stringent discharge limitations and testing requirements. 4. Land Application/Spray Irrigation This option could require the I-502 proponent to submit an engineering report to Ecology that describes AKART for the I-502 facility and a groundwater analysis of the site. Ecology would subsequently issue a state waste discharge permit that would require monitoring the wastewater and the groundwater. Contact the appropriate regional Ecology regional office for guidance on this option. ECY 070-s33 (08/16) Prohibited discharge options: 1. Drywells Drywells and infiltration trenches with perforated pipe are underground injection control wells and cannot be used for disposing of any industrial or commercial process wastewater. For more information see: http ://www.ecy.wa. gov/pro grams/wq/grndwtr/uic/index.html. 2. Stormwater Collection Systems The discharge of any industrial or commercial process wastewater into a stormwater system is prohibited. Other Environmental Considerations Ecology maintains a website: http://www.ecy.wa.gov/topics/marijuana.html providing information about other environmental considerations for I-502 licensees. Questions? Ecology encourages I-502 producers/processors to contact their county's regional Water Quality Program office for assistance in completing the wastewater discharge checklist.
