Section 250-RICR-150-10-8.14 - Minimum Standard 8: Land Uses with Higher Potential Pollutant LoadsA. Stormwater discharges from land uses with higher potential pollutant loads (LUHPPLs) require the use of specific source control and pollution prevention measures and the specific stormwater BMPs approved for such use. Allowable BMPs for LUHPPLs are included in the Table in § 8.14(D) of this Part. Many LUHPPLs require additional special permits such as a RIPDES Multi-Sector General Permit, and sector-specific required BMPs are included in Section VI of the Multi-Sector General Permit.B. Stormwater runoff from a LUHPPL shall not be recharged to groundwater, unless it has been adequately treated for the pollutant of concern as determined by the approving agency. The recharge prohibition at LUHPPLs applies only to stormwater discharges that come into contact with the area or activity on the site that may generate the higher potential pollutant load. In addition, infiltration practices should not be used where subsurface contamination is present from prior land use due to the increased threat of pollutant migration associated with increased hydraulic loading from infiltration systems, unless the contamination is removed and the site has been remediated, or if approved by DEM.C. The following land uses and activities are considered stormwater LUHPPLs: 1. Areas within an industrial site (as defined in § 1.4(A)(111) of this Subchapter) that are the location of activities subject to the RIPDES Multi-Sector General Permit (except where a No Exposure Certification for Exclusion from RIPDES Stormwater Permitting has been executed);2. Auto fueling facilities;3. Exterior vehicle service, maintenance and equipment cleaning areas;4. Road salt storage and loading areas (if exposed to rainfall);5. Outdoor storage and loading/unloading of hazardous substances; and6. Disposal sites as defined in § 8.5 of this Part.250 R.I. Code R. 250-RICR-150-10-8.14
