This data represents Environmental Resource Permit (ERP) applications. Data is supplied by the permit applicant and permitted by the St. Johns River Water Management District. This layer refers to permitting rules section 373.430 F.S., and 18 U.S.C. Section 1001. The applicant fills out a form 40C-4.900(1) and supplies the district with a location map of the project boundaries. In order to avoid undue hardship to the applicant, there are few restrictions on the type and quality of the map the applicant must supply. The location maps the applicant supplies are generally 1:24,000 USGS quadrangles, or in some cases digital orthographic quadrangle maps are provided.

As of August 23, 2012 this layer also includes the current set of FDEP 10/2 ("self certification") permits, as adopted by the Florida DEP in conjunction with the five Florida Water Management Districts, effective July 1, 2012. According to FDEP, these permits correspond to general permits for a "Stormwater Management System in Uplands serving less than 10 acres of total Land Area and less than 2 acres of impervious surfaces."

The FDEP 10/2 permits in this layer (PDSLIB.ERPSDE) are replaced nightly through an automated batch process from the FDEP ftp site (ftp.dep.state.fl.us). Only those 10/2 permits which have also been processed through the E-Reg system in SJRWMD are included in this layer, and attributed with the appropriate values from the E-Reg system.
