Change 1, 30 June 1995
Soil Amendments.  Soils should be tested for pH levels every 2
years.  Consult local agricultural extension agents.  The desired pH levels is
in the neutral range of 6 to 8.  The pH level can be raised if necessary by
adding hydrated, crushed, or pulverized limestone.
Vegetation.  Maintain vegetation on berms and drainageways.  Turf
grasses do an especially good job of retaining water and sediment on site.
Choose a grass with minimal watering and fertilizer needs. Rework the
projectile pocket in the berm by adding soil and grass often.  Use non-nitrate
based fertilizer.  Minimal amounts of nitrate based fertilizer may be used
during the initial grow-in period.  Remove any decaying wood or other plant
life on the range, particularly on the berm face and in the SDZ in near
proximity to the berm back.
Engineering Controls.  Prevent stormwater runoff from impact berms
from flowing directly into surface water environments. Divert surface water
runoff within the range (including the SDZ) to a vegetated detention basin or
infiltration area.  Provide straw bales , geotextile fabrics or other erosion
controls in drainage areas.  Slow the runoff and provide sediment traps.
Contaminant Monitoring.  The monitoring program is to provide early
indications of lead movement.  Sample the surface soil, surface water, and the
ground water for soluble lead, dissolved lead, total lead, and nitrates. The
sampling cycle should be based on range usage and site geohydrological
conditions.  Monitoring wells should be correlated with other existing wells
on the activity.  Monitoring wells are not required if the ground water table
is 20 feet or greater below the range surface.  On deep water tables note the
tests derived from the other activity wells,  Contact the activity
Environmental Engineer for support.
Reclamation and Recycling.  Remove lead in the berm face when there
is a noticeable lead mass that is causing RC.  The lead is to be sifted from
the soil on site.  Place the soil immediately back on the berm face.  Send the
sifted lead in containers to the, local recycling contractor or smelter.
a)  Health and Safety Plan.  Develop a site specific Health and
Safety Plan in cooperation with the local industrial hygienist before
excavating or removing any lead contaminated soil.  OSHA regulations 29 CFR
1910.1025 and 29 CFR 1926.62 apply.
Surface Danger Zones Over Water.  If the SDZ is to be oriented over
navigable water , obtain prior approval of the plan from CNO (Code N-411E).
a)  To obtain approval the following SDZ controls are required. The
SDZ's shall be included in construction drawings and written into the range
standard operating procedures (SOP):
