Code of Massachusetts Regulations
360 CMR - MASSACHUSETTS WATER RESOURCE AUTHORITY
Title 360 CMR 10.000 - Sewer Use
PROHIBITED WASTES AND LOCAL LIMITS
Section 10.026 - Compliance Measurement Location

Universal Citation: 360 CMR 10.000 MA Code of Regs 10.026
Current through Register 1531, September 27, 2024

All limitations imposed by 360 CMR 10.000 shall be applied at the end of the Pretreatment process line, at the end of the process line if there is no Pretreatment, or at or near the discharge location if there is no Pretreatment or process line. This shall not be construed to authorize a Person to introduce a pollutant into a wastestream after the compliance measurement location; rather, a sample taken at the compliance measurement location is intended to measure the pollutants in a discharge to the sewer before dilution of the wastestream.

Where it deems appropriate, the Authority may by permit or order impose alternative limits or compliance measurement locations to assure compliance with 360 CMR 10.000 and with federal, state, and local requirements. This may include use of the Combined Wastestream Formula when authorized by EPA regulations or use of a dilution factor when more than one stream is combined.

The Authority may require samples from individual process waste streams whether such waste streams are pretreated prior to discharge or not. The Authority may require that compliance measurement locations be clearly marked and/or photographed.
