Fla. Admin. Code Ann. R. 62-330.449 - General Permit for Construction, Operation, Maintenance, Alteration, Abandonment or Removal of Airport Airside Stormwater Management Systems

(1) A general permit is granted to the owner of a public or private airport or military airbase for the construction, alteration, abandonment, removal, operation, and maintenance of stormwater management systems that serve permanently-paved airside activities, which, for the purposes of this rule, are defined as those components of an airport, airbase, or runway used for aircraft taxiing, landing, takeoff, loading, unloading, service materials storage and service equipment parking.

(2) The stormwater management systems shall be:

(a) Designed such that the stormwater nutrient loading does not exceed the stormwater nutrient loading from natural vegetative communities. The calculation of such loadings shall be done using the methodology and data set forth in the Statewide Airport Stormwater Best Management Practices Manual, ("Airside BMP Manual") Florida Department of Transportation-Aviation Office (April 27, 2013), incorporated by reference herein (pages 1-63: http://www.flrules.org/Gateway/reference.asp?No=Ref-03183, pages 64-Appendix L: http://www.flrules.org/Gateway/reference.asp?No=Ref-03184). A copy may be obtained from the Agency, as described in subsection 62-330.010(5), F.A.C.

(b) Constructed, altered, operated, and maintained such that the runoff from airside activities drains directly to pervious areas that employ one or more of the following applicable structural Best Management Practices (BMPs):

1. Overland flow, as described in Section 605.a. of the Airside BMP Manual.

2. Dry retention basin, as described in Section 605.b. of the Airside BMP Manual.

3. Swales, as described in Section 605.c. of the Airside BMP Manual.

(c) This general permit is only authorized for use where post development site conditions comply with the criteria set forth above.

(3) The projects in subsection (2), above, must also be constructed, operated, and maintained to comply with the following design criteria and performance standards:

(a) There shall be no dredging or filling in wetlands or other surface waters other than those within existing stormwater management systems.

(b) Discharges cannot adversely affect the conveyance capacity of receiving waters, and cannot increase flooding of off-site property or to property not owned by the permittee, based on the design storm specified for the site locale.

(4) Stormwater management systems serving airside areas that consist of underdrains, wet detention systems, other retention methods, and/or alternative treatment systems do not qualify for authorization under this general permit.
