This magnetic computer tape contains data on all of the U.S. Environmental Protection Agency's P.L. 92-500 construction grant projects awarded since Feb. 1973. Each of the records contains applicant name and geographic data, a general description of the project and EPA funding data. Both the original EPA funds awarded to the project and the cumulative EPA funding is presented in the records. Usually three projects are awarded sequentially in the P. L. 92-500 process of building a treatment works as follows: a step one project for facility planning, followed by a step 2 award for construction drawing and specifications, and a step 3 for actual construction. However, in many cases in the past an applicant was reimbursed for step 1 and step 2 work within a single step 3 project award. Thus, EPA funding of the treatment works started with a step 3 award. In general it takes from 6 months to a year to complete a step 1 project and approximately one year to complete a step 2 project. Therefore, from the time a step 1 appears in the data base, it could take up to two years for the step 3 project to be awarded and construction initiated.
