Local PM10 Emissions Reduced
EPA is proposing to approve a Minnesota plan that lowers allowable PM10 (tiny dust) emissions at the Metropolitan Council Wastewater Treatment Plant in Saint Paul, Ramsey County. The plan lowers several equipment limits (for example, fluidized bed incinerators from 2.01 to 1.70 lbs/hr, boilers from 25.82 to 18.54 lbs/day, and ash vacuum from 0.05 to 0.005 gr/dscf) and the facility modeled a combined decrease of 6.3 tons per year in allowable PM10 emissions.
No Significant Small-Business Costs
EPA states this action approves State law and is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act. The rule text also says no big money changes are expected.
