• <br /> Popach Short Plat—2 Lots <br /> Element# 9: Control Pollutants <br />• All pollutants from construction vehicles will be contained and disposed of in the <br /> approved manner consistent with state environmental policies. Any vehicle <br /> maintenance will be performed by authorized mechanics using drip pans and waste <br /> containment vessels. All pollutants will be disposed offsite at approved facilities. <br /> Element# 10: Control De-Watering <br />• De-watering of the site is not expected. If dewatering of the site is needed, all ground <br /> water removed shall be retained and recharged into the ground after de-watering has <br /> been finalized. <br /> Element# 11: Maintain BMP's <br />• All Temporary Erosion and Sedimentation Control (TESC) devices and equipment <br /> will be inspected and maintained on a weekly basis if not sooner,based on storm <br /> events contributing to runoff. When construction is complete and the site is stabilized, <br /> any existing sediment will be removed and stabilized onsite. <br /> Element# 12: Manage the Project <br />• A general construction manager will manage the project for or by the owners. The <br /> construction manager shall maintain all of the above items in order to minimize <br /> sediment transport and turbid water leaving the site. His job will entail continual <br /> observation of the grading operations to ensure minimal effects to adjacent properties <br /> and offsite waterways. <br /> Element# 13: Protect On-Site Stormwater BMPs <br /> On-site stormwater BMPs include permeable driving surfaces along with above <br /> ground bio-retention planter areas. New infiltration areas shall be protected from <br /> compaction by heavy machinery to the maximum extent feasible. <br /> Minimal Requirement # 3: Water Pollution Source Control <br /> Project consists entirely of residential development. Water Pollution Source Control <br /> does not apply. <br /> Minimum Requirement # 4: Preservation of Natural Drainage Systems <br /> and Outfalls, and provisions of off-site mitigation <br /> This site contains one basin that drains into a receiving water less than IA mile from <br /> the site (Pigeon Creek#1). Natural drainage discharge points will be maintained <br /> through the development plan of the site. <br /> Minimum Requirement #5 On-Site Storm Water Management <br /> Due to the project proposing more than 10,000 sf. of new impervious surfaces, <br /> Minimum Requirements #1 through#9 must be met. Because the project triggers <br /> analysis of Minimum Requirement#7, the project must meet either the Low Impact <br /> Development Performance Standard or List#2 in section 2.5.5 of Volume I of the <br /> 2014 DOE SMMWW. This project has chosen to fulfill the requirements of List#2. <br /> WESTERN ENGINEERS,INC. 11 PROJECT:15-1463-A <br />
