What guidance and information has the Department developed with respect to trading?
The Department has developed an Internal Management Directive (IMD) for Water Quality Credit Trading. The IMD may be viewed on the Department’s Water Quality Trading webpage. The Water Quality Trading IMD represents DEQ’s current directions to staff on acceptable water quality trades between and among point sources and nonpoint sources. This policy document is based in part on the EPA 2003 Water Quality Trading Policy, discussions with EPA Region 10 staff, and DEQ’s experiences with trading to date.
