What it does

Summary by the , the Legislature's nonpartisan drafting office. It's their wording, not ours.

Generally, under current law, a person may not discharge pollutants into the waters of this state from a point source (such as a pipe) without a permit from the Department of Natural Resources (DNR) that specifies limits on the discharge of water pollutants. Current law requires DNR to administer at least one pilot project to evaluate the trading of water pollution credits. Under a pilot project, a person who is required to obtain a water pollution permit may be authorized to discharge more pollutants than would otherwise be allowed if the person reaches an agreement under which another person agrees to reduce the amount of water pollution that the other person causes or if the person reaches an agreement to provide money that DNR or a local government uses to reduce water pollution.

This bill requires DNR to administer a program, rather than at least one pilot project, for the trading of water pollution credits. In addition to providing for agreements as under current law, the bill provides that DNR may authorize a person who is required to obtain two water pollution permits to discharge more pollutants than would otherwise be allowed under one permit if the person agrees to reduce the amount of water pollution below what would otherwise be allowed under the second permit. The bill also provides that DNR may authorize a person to discharge more pollutants than would otherwise be allowed if the person agrees to construct a project or implement a plan that results in reducing water pollution from sources other than the permitted source.

Read the full summary

Under current law and under the bill, a water pollution credit trading agreement is only allowed if it results in an improvement in water quality and if the increase and the reduction involve the same pollutant or the same water quality standard. Under current law, a water pollution trading project may only be conducted within a project area that meets specified criteria. This bill eliminates the requirement concerning a project area, but requires that the increase and the reduction in pollution occur within the same water basin or portion of a water basin, as determined by DNR. Under current law, the term of a water pollution trading agreement may not exceed five years. This bill eliminates the restriction on the term of an agreement. Both current law and the bill require that trading of water pollution credits be conducted in accordance with the federal Water Pollution Control Act.
