Finish grading provides the necessary slopes for drainage of rain 

 runoff. Unless a separate system is provided, polluted water from the 

 pipe-coating process would drain to the same collection points. Buffer 

 areas of natural terrain provided along the edges of watercourses aid soil 

 stability and runoff detention and purification. Those along adjacent 

 property lines reduce noise effects from sand or shot-blasting, pipe 

 handling, and other operations. 



Leveling the yard surface may require the use of additional dredged 

 or trucked material to fill depressions, to raise the land surface above 

 flood elevations, or to solve other problems. Most of the work area is 

 left unsurfaced, except for sand bed and sand berm requirements in pipe 

 curing and storage areas. 



Where piers are not considered, substantial filling along the shore- 

 line may be needed to backfill behind bulkheads. If the pipe-coating 

 facility is located inland with a road or rail link to a marine loading 

 terminal, this type of filling would be minimal.

Access roads are required from main or secondary roads to the 

 property, at which point they may change from paved to unpaved surfaces. 

 Travel ways in the yard often are left unpaved to allow greater flexibility 

 in storage and handling of pipe, and to reduce construction expenses. 



Underground utility, wastewater, and related systems are "roughed 

 in" during this stage, including excavation, pipe or conduit laying, 

 and regrading of main lines. Provisions are made for sumps, collectors, 

 sediment basins, and other wastewater systems. Excess materials from 

 excavation may require disposal.

Commuting traffic requirements of a pipe-coating yard are moderate, 

 while material shipment by highway may put a comparatively heavy load on 

 the local highway system, particularly in the absence of a railroad 

 connection. The amount of miscellaneous raw material used at a typical 

 yard averages 200,000 tons per year. Traffic volume varies greatly 

 between busy and slack periods. However, daily or weekly deliveries of 

 fuels, cement, primer, and mastic can be expected during periods of full 

 operation. 



The pipe to be coated is transported by rail, barge, or ship; because 

 of its weight, highway transport is normally infeasible. Railroad
