Sign-up will stay open until the hearing gets filled up, so sign up ASAP:
The Air Quality Control Commission public comment period is next Wednesday December 16 starting at 4:30 PM.  The Commission will be taking comment on proposed rules to address ozone pollution in the Denver Metro/North Front Range region.  Many CCLC groups are participating as parties to the rulemaking and have raised concerns that the proposed rules do not sufficiently rein in fossil fuel pollution in the region.  WildEarth Guardians has actually submitted an alternate proposal calling for reductions in motor vehicle emissions and pollution offsets from new stationary sources, more background here,
