Background and Analysis:
Background and analysis have not changed from first to second reading.
The LOTT Clean Water Alliance (LOTT) provides wastewater treatment for the City of Olympia as well as Thurston County and the cities of Lacey and Tumwater. LOTT is a non-profit 501(c)3 corporation, formed by the four government partners under an interlocal agreement. The LOTT Board is composed of one elected official appointed by each of the partner jurisdictions.
The LOTT Budd Inlet Treatment Plant must comply with State and Federal laws, including the Clean Water Act (33 United States Code, Section 1251 et seq.) and the General Pretreatment Regulations (40 Code of Federal Regulations Part 403). This work includes monitoring waste streams from industrial dischargers; establishing local limits for metals discharge; issuing permits to Significant Industrial Dischargers; and enforcing the prohibited discharge standards for materials that would pass through treatment, interfere with the treatment process, or could damage sewer infrastructure or endanger public workers.
The pretreatment regulations adopted by the LOTT Board are included in the municipal codes of all the LOTT partner agencies. In Olympia, these regulations are located in Olympia Municipal Code Title 13.20.
Over the last seven years, LOTT has worked in concert with the cities of Lacey, Olympia, and Tumwater, as well as Thurston County and the Department of Ecology to review the pretreatment regulations and prepare revisions to provide protection to the LOTT treatment system. These revisions have been reviewed and unanimously approved by the LOTT Board. Under the terms of the LOTT Interlocal Agreement, partner agencies have 90 days to adopt the changes to the pretreatment regulations into their municipal codes.
The pretreatment regulations limit what can be discharged into the municipal sewer system. This includes prohibitions on things like motor oil, acidic wastes, or strong oxidizers. Discharges from industrial facilities are controlled; this may involve treatment of the waste stream before it can be discharged. Industrial sites are permitted and required to monitor and report information about their waste to LOTT. The regulations also control the discharge of fats and oils that can plug sewers and result in overflows. Businesses discharging fats and oils are required to install and maintain grease traps at their facilities.
Revisions to these regulations are needed to address State Department of Ecology requirements, make minor typographic corrections, and establish appeal procedures for ordinance violations. These changes include defining and codifying discharge limits for molybdenum discharges (US EPA pollutant of concern); updating requirements and authority for dental office reporting, best management practices and to install and maintain dental amalgam separators; and include specific time-based cleaning frequencies, defined cleaning methods, and establish requirements for repairs and fixture connections.
