On Sept. 19, 2013, EPA approved a provision in Oregon’s Antidegradation rule stating that certain nonpoint source activities (rotation of grazing pastures and cropping) do not require an antidegradation review. Because the rule has been in place since 2003, this EPA action does not require changes to DEQ’s implementation of the antidegradation policy.
On Aug. 8, 2013, DEQ received a letter of review from EPA on Oregon's antidegradation implementation methods as described in the internal guidance document above. DEQ developed on a series of memos clarifying implementation procedures to address issues raised in EPA's review.
