EXPECTED POLLUTANTS WILL BE MINIMAL IN NATURE, POST DEVELOPMENT. OIL, GREASE, ANTIFREEZE, GASOLINE, ETC. MAY OCCUR IN LIMITED AMOUNTS AS A RESULT OF THE MAJORITY OF THIS PROJECT SITE BEING USED FOR TENANT PARKING. THE ONLY OTHER REASONABLY FORESEEN POLLUTION FROM THIS SITE WILL BE LITTER AND TRASH LEFT BY VISITORS TO THE FACILITY. 2. THE POST CONSTRUCTION STORMWATER QUALITY BMP IS A VORTECHS STORMWATER TREATMENT UNIT, WHICH WAS APPROVED AS PART OF THE MASTERPLAN AND PROVIDED DURING CONSTRUCTION OF THE PARKWOOD WEST OFFICE PARK (PHASE 1). THIS UNIT WAS INSTALLED AT THE DISCHARGE POINT OF THE UNDERGROUND DETENTION SYSTEM AT THE NORTHWEST CORNER OF THE SITE, JUST BEFORE THE SITE OUTLETS TO THE INDOT RIGHT -OF -WAY ALONG 1 -465.

FINAL STABILIZATION OF THE SITE WILL BE ACCOMPLISHED USING PERMANENT SEEDING OF ALL OPEN AREAS, LANDSCAPING WITH MULCH. 3. POST CONSTRUCTION STORMWATER QUALITY WILL BE ACCOMPLISHED THROUGH THE USE OF THE EXISTING VORTECHS UNIT. THIS STRUCTURE IS A SWIRL UNIT THAT REMOVES SEDIMENT, DEBRIS, AND HYDROCARBONS FROM THE STORMWATER THAT FLOWS THROUGH IT. NO RIPARIAN WETLANDS EXIST ON OR ADJACENT TO THE SITE. 4. MAINTENANCE OF ALL STORMWATER POLLUTION PREVENTION MEASURES WILL BE THE RESPONSIBILITY OF THE PROJECT OWNER, UTILIZING PROCEDURES OUTLINED ON THESE PLANS.
