Section ENV.06.05 — Groundwater Protection Best Management Practices
The following BMPs shall be adopted on the Reservation, as applicable, to help protect the quality of the groundwater. These BMPs shall be followed, unless they are superseded by more stringent requirements under this Ordinance or other applicable laws.
(a) Handle and store materials that could contaminate groundwater in a secure location with secondary containment. When not in immediate use, keep such materials in closed containers.
(b) Properly dispose of waste materials, unused or unwanted chemicals, and used batteries in a timely fashion.
(c) Adopt practices for the regular inspection and maintenance of potential sources of groundwater contamination.
(d) Have plans and equipment in place to promptly contain and clean spills. Dispose of cleaning materials properly.
(e) Eliminate floor drain discharges to the ground, septic systems, storm sewers or any surface water body.
(f) Single-walled underground fuel storage tanks should be replaced with above-ground or basement fuel storage tanks or monitored buried tanks conforming with industry standards.
(g) Mix and load pesticides, fertilizer or any other substance that could contaminate groundwater in a way that prevents leaks, spills or overflows onto the soil. Dispose of cleaning rancid from sprayer tanks and equipment properly.
(h) Match the application of pesticides and fertilizers to the actual need and uptake rates. Avoid chemicals with high leaching potential on highly permeable soils.
(i) Seal floor surfaces with an impermeable material that is resistant to substances used in the facility at commercial and/or industrial facilities.
(j) Isolate spill-prone areas from floor drains with the use of berms.
(k) Closed cooling water systems should be adopted.
(l) Consolidate and segregate waste-generating operations in a secure area.
(m) Proper disposal systems are needed for wastewater generated at commercial and/or industrial facilities or use holding tanks for such wastewater.
