Minn. R. agency 167, ch. 7049, pt. 7049.0420
For pollutants that are not being discharged currently, the POTW authority may apply for authorization to give removal credits prior to the initial discharge of the pollutant, such as for new or modified facilities or production changes. Consistent removal shall be based provisionally on data from treatability studies or demonstrated removal at other treatment facilities when the quality and quantity of influent are similar. Within 18 months after the commencement of discharge of pollutants in question, consistent removal must be demonstrated pursuant to parts 7049.0400 and 7049.0410. If within 18 months after the commencement of the discharge of the pollutant in question the POTW cannot demonstrate consistent removal pursuant to parts 7049.0360 to 7049.0470, the authority to grant provisional removal credits shall be terminated by the agency and all industrial users to whom the revised discharge limits had been applied shall achieve compliance with the applicable categorical pretreatment standards within a reasonable time, not to exceed the period of time prescribed in the applicable categorical pretreatment standards, as may be specified by the agency.
