<br />PROJECT DESCRIPTION:
<br />A STORMWATER POLLUTION PREVENTION PLAN (SWPPP) HAS BEEN PREPARED IN CONFORMANCE WITH THE
<br />GENERAL PERMIT AUTHORIZATION TO DISCHARGE STORMWATER ASSOCIATED WITH CONSTRUCTION ACTIVITY
<br />UNDER THE NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES)/STATE DISPOSAL SYSTEM (SDS)
<br />CONSTRUCTION STORMWATER PERMIT. THE PROJECT WILL DISTURB LESS THAN ONE ACRE, HOWEVER ALL
<br />SITE WORK SHALL FOLLOW THE PERMIT GUIDELINES.
<br />THE GOAL OF POLLUTION PREVENTION EFFORTS DURING PROJECT CONSTRUCTION IS TO CONTROL SOIL AND
<br />POLLUTANTS ON THE SITE AND PREVENT THEM FROM LEAVING THE PROJECT SITE AND FLOWING TO SURFACE
<br />WATERS. THE PURPOSE OF THIS SWPPP IS TO PROVIDE GUIDELINES FOR ACHIEVING THAT GOAL. THE SWPPP
<br />MUST BE KEPT ONSITE AND UPDATED AS NECESSARY DURING THE COURSE OF CONSTRUCTION TO KEEP IT
<br />CURRENT WITH ANY MODIFICATIONS TO THE POLLUTION CONTROL MEASURES BEING UTILIZED.
<br />THIS PROJECT CONSISTS OF THE ADDITION OF TWO ABOVE -GRADE FUEL TANKS AND ASSOCIATED ACCESS
<br />ROADS AND PAVED STORAGE AREAS LOCATED ON THE NORTH SIDE OF PROPERTY.
<br />THE PROPOSED STORMWATER MANAGEMENT DESIGN WILL MEET THE REQUIREMENTS OF THE CITY OF
<br />RAMSEY AND THE LOWER RUM RIVER WATERSHED MANAGEMENT ORGANIZATION. THIS PROJECT IS NOT
<br />REQUIRED TO MEET THE MPCA PERMANENT STORMWATER MANAGEMENT REQUIREMENTS BECAUSE THE
<br />DISTURBED AREA IS LESS THAN ONE ACRE.
<br />REGULATORY CONTEXT:
<br />DISCHARGE TO SPECIAL OR IMPAIRED WATERS WITHIN ONE MILE OF SITE:

<br />WATER ON THE MPCA'S 303(D) IMPAIRED WATERS LIST FOR FECAL COLIFORM, MERCURY IN FISH TISSUE,
<br />NUTRIENTS, AND PCBs IN FISH TISSUE. THESE IMPAIRMENTS ARE CONSIDERED CONSTRUCTION RELATED
<br />AND ALL BMPS SHOULD FOLLOW ITEMS 23.9 AND 23.10 IN THE MPCA PERMIT GUIDELINES.
<br />PLACEMENT OF FILL IN WATERS OF THE STATE:
<br />- N/A
<br />DRINKING WATER SUPPLY MANAGEMENT AREA:
<br />- N/A
<br />THE PROJECT STORMWATER DISCHARGE IS NOT ANTICIPATED TO IMPACT ANY OF THE FOLLOWING:
<br />- OUTSTANDING RESOURCE VALUE WATERS, TROUT WATERS, WETLANDS, CALCAREOUS FENS, PROPERTIES
