Minnesota Administrative Rules

7049.0460 AUTHORIZATION TO GIVE REMOVAL CREDITS.

Subpart 1.

Effect of authorization.

When a POTW authority has received authorization to grant removal credits for a particular pollutant regulated in a categorical pretreatment standard, it may automatically extend that removal credit to the same pollutant when it is regulated in other categorical standards, unless granting the removal credit will cause the POTW to violate the sludge requirements identified in part 7049.0380, item A, subitem (4), or its national pollutant discharge elimination system permit limits and conditions as required by part 7049.0380, item A, subitem (5). If a POTW authority elects at a later time to extend removal credits to a certain categorical pretreatment standard, industrial subcategory, or one or more industrial users that initially were not granted removal credits, the POTW shall notify the agency.

Subp. 2.

Inclusion in POTW permit.

When authority is granted, the removal credits shall be included in the POTW's national pollutant discharge elimination system permit as soon as possible and become an enforceable requirement of the POTW's national pollutant discharge elimination system permit. The removal credits remain in effect for the term of the POTW's national pollutant discharge elimination system permit, provided the POTW maintains compliance with the conditions in part 7049.0470.

Subp. 3.

Compliance monitoring.

Following authorization to give removal credits, and at intervals specified by the agency, but in no case less than once per year, the POTW authority shall continue to monitor and report on the POTW plant's removal capabilities. A minimum of one representative sample per month during the reporting period is required and all sampling data must be included in the POTW's compliance report.
