Emission reduction credits

The DNR's Air Management Program tracks emission reduction credits (ERCs) as prescribed under s NR 408.05 and .06, Wis. Adm. Code. These credits are used in several southeastern Wisconsin counties to offset emissions from new construction.

Section NR 408.05, Wis. Adm. Code, requires ERCs be used to "sufficiently offset" the emissions increase from a new or modified source.

Section NR 408.06, Wis. Adm. Code, supplies the criteria for quantifying the ERCs generated and thus the offsets used. When generated, the ERCs must be permanent, quantifiable, surplus (i.e., not to be used in the future), real and federally enforceable. The ERCs are certified under a permit with federally enforceable conditions. The reductions to meet reasonably available control technology (RACT) cannot be certified as ERCs to be used as offsets. Therefore as such the credits generated at one point may be reduced as new volatile organic compound (VOC) or nitrogen oxide (NOx) RACTs are promulgated. These reduction of "values" of these credits are checked by DNR when they are used as offsets for construction permits.

The offset ratio (i.e, the amount of ERCs needed to reduce one ton of VOC or NOx in a construction permit) differs according to nonattainment designation. Currently, the ozone nonattainment areas in the state are either designated as moderate with an offset ratio of at least 1.15 to 1, according to s. NR 408.06(4)(b), Wis. Adm. Code, or as basic (for Door, Kewaunee and Manitowoc Counties) with an offset ratio of 1 to 1. Wisconsin attains standards for NOx in all counties so the current NOx offset ratio is 1 to 1.

The DNR has attempted to compile a complete list of ERCs based on available documents. If you believe that an ERC should be part of the list or know that a company has completed a transaction and it no longer owns an ERC, please contact Ralph Patterson (608-267-7546) so that he can update the list.
