Because all pesticides are toxic to plants and animals, they may pose an unacceptable risk to human health and the environment. The data is difficult and expensive to develop and must prove that the chemical is effective and safe to humans and the environment. Labels must be placed on pesticide products that indicate approved uses and restrictions. All private facilities having more than 10 employees must comply with the OSH Act requirements. The CAA also addresses specific air pollution problems such as hazardous air pollutants, stratospheric ozone depletion, and acid rain.
States issue air emission permits to facilities.
This act is considered largely successful because significant improvements have been made in the quality of the nation's waterways since its enactment. Permits contain either effluent limits or require the installation of specific pollutant treatment. Permit holders must monitor discharges, collect data, and keep records of the pollutant levels of their effluents. Transporters and disposal facilities must adhere to similar requirements for record keeping as well as for monitoring the environment. Facilities must work with state and local entities to develop emergency response plans in case of an accidental release.
