(8) The postconstruction storm water pollution prevention plan. 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.

POSTCONSTRUCTION STORM WATER POLLUTION PREVENTION PLAN
Following completion of mining activities, the site will be graded with slopes no steeper than
3 to 1 (horizontal to vertical), with a flat bottom with drainage routed to the south to the existing
Martin Marietta North Indianapolis Plant. 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.
