Congressional Budget Office Cost Estimate: H.R. 872, Reducing Regulatory Burdens Act of 2011 [open pdf - 16KB]
"H.R. 872 would prohibit the Environmental Protection Agency (EPA) and states authorized to issue National Pollutant Discharge Elimination System (NPDES) permits from requiring a permit for some discharges of pesticides authorized for use under the Federal Insecticide, Fungicide, Rodenticide Act (FIFRA). Under the bill, public and private entities would no longer need to obtain an NPDES permit for discharges of pesticides from point sources except in cases where the application of the pesticide would not fall under FIFRA, or in cases where the discharge is regulated as a stormwater, municipal, or industrial discharge under the Clean Water Act. Under a recent court ruling, the requirement to obtain an NPDES permit will become effective on April 9, 2011; at that time, pesticide applications not covered by an NPDES permit will be subject to a fine."
