NR 220.12(1)
(1) “Effluent Limitation Guidelines” or “ELGs” are federal or state technology based guidelines or standards that are used to establish effluent limitations for industrial categories or classes of dischargers. They include federal guidelines, standards, and limitations that are established under
33 USC 1311,
1314,
1316,

1342 and
1361 and state promulgated guidelines, standards, and limitations in chs.

NR 220.12(2)
(2) “Fundamentally different factors variance” or “FDFV” means a variance or an adjustment to an effluent limitation when data specific to a permittee indicates the presence of factors that are fundamentally different from the factors considered by EPA in development of the effluent limitation guidelines
33 USC 1311 and
1314.

Listed industrial categories. In the event that the EPA promulgates an effluent limitation guideline for a category or class of point sources listed in s.
NR 220.02 that is more stringent than the promulgated effluent limitation guideline for that category or class, the department shall include an effluent limitation based on the EPA-promulgated effluent limitation guideline in an issued, reissued, or modified WPDES permit for a point source that belongs to the federal category or class of point sources in accordance with the federally required compliance date.
NR 220.13(2)
(2)
Industrial categories not specifically listed. In the event that the EPA promulgates an effluent limitation guideline for a category or class of point sources not listed in s.
NR 220.02, the department shall include an effluent limitation based on the EPA-promulgated effluent limitation guideline in an issued, reissued, or modified WPDES permit for a point source that belongs to the federal category or class of point sources in accordance with the federally required compliance date.
NR 220.13(3)
(3)
Less stringent limitations. If a promulgated federal effluent limitation guideline results in an effluent limitation that is less stringent than an existing applicable technology based limitation contained in a WPDES permit, the department may only include the less stringent limitation if the antibacksliding requirements in ch.
NR 207 are satisfied.
NR 220.13(4)
(4)
Compliance. Prior to any permit modification, revocation and reissuance, or reissuance to incorporate a limitation for a toxic substance based on a revised federal effluent guideline promulgated under
33 USC 1317, the permittee shall comply with the federally promulgated guideline by the required compliance date even if the permit has not yet been modified, revoked and reissued, or reissued to include a limitation based on the revised guideline.
