Welcome to the Delaware Targeting And Planning Tool
The Delaware Targeting and Planning Tool (DTAP) is designed to facilitate identification of opportunities for achieving load reductions required by TMDLs, develop implementation plans, and support long-term evaluation of nonpoint source nitrogen, phosphorus, sediment, and bacteria reductions.
The Delaware Natural Resources and Environmental Control (DNREC) staff use DTAP to answer questions such as:
- What is the effect of urban stormwater treatment’s anticipated impact on pollutant loads?
- What are the anticipated effects of tillage on nutrients and sediment?
- What is the anticipated effect of various combinations of BMPs on limiting nutrient and sediment runoff?
- At what location should BMPs be implemented to reduce the most pollutants?
- Which BMPs are most cost-effective?
To answer these questions, users identify contaminant loads in a defined geographic location and determine which are the most cost-effective BMPs that can be targeted to control the pollutants. The geographic area includes the portions of Delaware that are within the Piedmont, Delaware and Inland Bays, and Atlantic Ocean Basins. Beneficiaries of DTAP include MS4s, U.S. EPA, DNREC, and all those who care about clean water in Delaware.
