If certain species in this mix are unavailable, substitutions may be submitted for approval. The mix shall be applied as specified per hectare (acre). The method of planting shall be by means of hydroseeding or by means of a hand method with a minimal amount of mulch applied in a separate operation. Fertilizer shall not be added to this seed mixture. Federal, state, and local requirements should be observed for any stationary above ground storage tanks. In the event of a spill, contact the local fire department at (317) 776 -6336. inspection and Maintenance Vehicles and equipment should be inspected each day for leaks. Leaks shall be repaired immediately or the equipment shall be removed from the site. Appropriate and ample spill cleanup materials and supplies shall be kept in the designated refueling areas. Any spill shall be immediately cleanup up and the contaminated materials and soil shall be properly disposed of.

A bermed concrete washout area shall be established not less than 50 feet from a drainage facility or watercourse. The location of the concrete washout area shall be indicated on the pollution prevention plan. A temporary pit shall be established with in the concrete washout area where concrete can set, be broken up, and disposed of properly. The washing of concrete trucks and equipment shall only occur in this designated concrete washout area. No excess concrete shall be disposed of on site unless inside the concrete washout area. Inspection and Maintenance The project superintendent or foreman shall be made responsible to ensure that concrete washout areas are properly constructed and that concrete washing activities only occur in these areas. The temporary pit shall be cleaned and the material properly disposed of before the pit is allowed to over flow. Sanitary /Septic Contractors and subcontractors must comply with all state and local sanitary sewer, portable toilet or septic system regulations. Sanitary facilities shall be provided at the site by each contractor or subcontractor throughout construction activities. The sanitary facilities should be utilized by all construction personnel and be serviced regularly. All expenses associated with providing sanitary facilities are the responsibility of the contractors and subcontractors. The location of any sanitary facilities should be indicated on the stormwater pollution prevention plan by the operator following on -site location of said facilities. Dust Control /Off -Site Vehicle Tracking During construction, water trucks should be used, as needed, by each contractor or subcontractor to reduce dust. After construction, the site should be stabilized to reduce dust. Construction traffic should enter and exit the site at a Construction Entrance with a rock pad or equivalent device. The purpose of the rock pad is to minimize the amount of soil and mud that is tracked onto existing streets. If sediment escapes the construction site, offsite accumulations of sediment must be removed at a frequency sufficient to minimize offsite impacts. Water Source Water used to establish and maintain grass, to control dust, and for other construction purposes must originate from a public water supply or private well approved by the State or local health department.
