This document is a regulatory specification for wastewater effluent disposal and treatment systems, specifically detailing technical requirements and monitoring standards. The regulations cover new and proposed wastewater disposal systems, which must consist of a primary disposal component and a 100 percent back-up disposal component, each designed to handle peak flow according to county design standards. Key requirements include:

Sampling and monitoring protocols mandate specific testing frequencies based on daily wastewater flow volumes, including composite sampling, biochemical oxygen demand (BODs) limits, and suspended solids measurements. Treatment works must track and report multiple parameters such as total daily flow, chlorine residual, dissolved oxygen, and pH levels. Owners or authorized agents are required to submit laboratory data twice annually, maintain log books of operational details, and ensure effluent meets specified limits for various water quality metrics. The document also addresses alternative effluent limitations and sampling procedures for different scales of wastewater treatment facilities.
