What is LINAP?

LINAP is a multiyear initiative to reduce nitrogen in Long Island's surface and ground waters by DEC, the Long Island Regional Planning Council (LIRPC), and Suffolk and Nassau counties, with input from multiple partners and stakeholders. More information about LINAP is available below and on the pages under the "Important Links" section on the right side of this page.


The primary goals of LINAP are to:

  • Identify sources of nitrogen to surface waters and groundwater
  • Establish nitrogen reduction endpoints
  • Develop an implementation plan to achieve reductions

Fact Sheets

Fertilizer Fact Sheets have been developed from the information gathered from the workgroup. The purpose of these fact sheets are to give people additional information to help them care for their lawns while considering the environmental impacts. A fact sheet on Fertilizer Application Timing and another on Managing Irrigation are available on the web site.

In addition, the fact sheets are available for download and can be printed for personal and professional use.

Recent Articles

The summer 2017 issue of the New York Water Environment Association's (NYWEA) ClearWaters magazine was dedicated to LINAP. Articles by DEC, LIRPC, Nassau and Suffolk counties, consultants and researchers cover topics such as the LINAP structure, completed and ongoing projects, and new technology. Several of the articles are available for download on NYWEA's webpage, or a complete copy of the magazine can be ordered (a direct link is in the "Links Leaving DEC's Website" section on the right-hand column of this page).
