The plan must include the following information: (A) A description of potential pollution sources from the proposed land use, that may reasonably be expected to add a significant amount of pollutants to storm water discharges. See Post Construction Storm Water Pollution Prevention Plan beginning on page 8-2. (8) Location, dimensions, detailed specifications, and construction details of all postconstruction storm water quality measures. N/A. All water will be directed to the south to an existing lake. (C) A description of measures that will be installed to control pollutants in storm water discharges that will occur after construction activities have been completed. Such practices include infiltration of run-off, flow reduction by use of open vegetated swales and natural depressions, buffer strip and riparian zone preservation, filter strip creation, minimization of land disturbance and surface imperviousness, maximization of open space, and storm water retention and detection ponds. See Post Construction Storm Water Pollution Prevention Plan beginning on page 8-2. (0) A sequence describing when each postconstruction storm water quality measure will be installed. See Post Construction Storm Water Pollution Prevention Plan beginning on page 8-2. (E) Storm water quality measures that will remove or minimize pollutants from storm water run-off. See Post Construction Storm Water Pollution Prevention Plan beginning on page 8-2. (F) Storm water quality measures that will be implemented to prevent or minimize adverse impacts to stream and riparian habitat. See Post Construction Storm Water Pollution Prevention Plan beginning on page 8-2. (G) A narrative description of the maintenance guidelines for all postconstruction storm water quality measures to facilitate their proper long term function. This narrative description shall be made available to future parties who will assume responsibility for the operation and maintenance of the postconstruction storm water quality measures.

The site will be revegetated in accordance with the Erosion and Sedimentation Control and Planting Plan - Post Mining, provided in Mueller Property South Sand and Gravel Operation Erosion and Sediment Control Report, located in Section 6 of this Construction Plan. Temporary erosion and sediment controls will remain in place until the contributing drainage areas are stabilized. Collection channels will be developed, as necessary, to control and direct surface water flow to the existing North Indianapolis Plant. This will allow for dry pit conditions during reclamation. The revegetation will promote infiltration of runoff. A maintenance agreement for the relocated Blue Woods Creek will be in place with the Hamilton County Surveyor. DESCRIPTION OF POTENTIAL POLLUTANT SOURCES U There are no potential pollutant sources associated with the post-mining land use that may reasonably be expected to add a significant amount of pollutants to storm water discharges.
