(A) Applicability.
(1) The requirements under this section are the same as those under § 54.08.
(2) New public or private fueling areas or those that replace existing tank systems, regardless of tank size or total land disturbance.
(B) Exemptions.
(1) The exemptions under this section are the same as those under § 54.08.
(2) Construction activities associated with a single-family residential dwelling disturbing less than one acre, when the dwelling is not part of a
larger common plan of development or sale; or individual building lots within a larger permitted project.
(3) Land-disturbing activities where there will be no additional impervious surfaces associated with the final completed project, including, but not limited to, ditch construction/reconstruction and utility installation/maintenance activities.
(C) Minimum requirements. A project site owner shall meet the following minimum requirements.
(1) When using infiltration measures, take into consideration the pollutants associated with runoff and the potential to contaminate groundwater resources. When there is a potential for contamination, choose alternative measures or measures that pretreat runoff to eliminate or reduce the pollutants of concern.
(2) Where there is a potential for groundwater contamination, including in wellhead protection areas, measures shall be implemented that pretreat the water quality volume or flow rate to eliminate or reduce the pollutants of concern, including total suspended solids (TSS) and oil/grease at a minimum.
(3) Registration of any Class V injection well with EPA Region 5.
(4) All post-construction stormwater quality and quantity measures necessary to comply with this chapter must be implemented per the approved construction plan, and sufficient to satisfy the requirements of the CSGP and the Indiana Stormwater Quality Manual.
(5) Any fueling area, publicly- or privately-owned, that installs or replaces fuel tanks must install appropriate post-construction stormwater quality treatment measures to reduce lead, copper, zinc, and polyaromatic hydrocarbons in stormwater runoff. Treatment must include the water quality volume or flow rate.
(6) Performance standards identified in the CSGP.
(7) The Board may require the use of any storage, infiltration, filtering, and/or vegetative practices to reduce the impact of pollutants on stormwater runoff. Where appropriate, and to the extent of the Stormwater Management Department’s authority, the planning procedures may also include the following:
(a) Buffer strip and riparian zone preservation;
(b) Filter strip creation;
(c) Minimization of land disturbance and surface imperviousness;
(d) Minimization of directly-connected impervious areas;
(e) Maximization of open space;
(f) Directing the community’s growth away from sensitive areas and towards areas that can support growth without compromising water quality.
