Air Management Services resources

Air quality, emissions and compliance information

  • Emission inventory guidelines for facilities.
  • If your facility is required to submit an annual emission inventory, register your facility with the Pennsylvania Department of Environmental Protection.
  • The EPA’s AP-42 is a compilation of air emissions factors to assist you with emission calculations.
  • Use ECHO (Enforcement & Compliance History Online) to determine whether compliance inspections have been conducted by EPA or state/local government, violations were detected, enforcement actions were taken, and penalties were assessed in response to environmental law violations.
  • The AQI (Air Quality Index) tells you how clean the air is and whether it will affect your health. Through AIRNow, EPA, NOAA, NPS, state, and local agencies work together to report current and forecast conditions for ozone and particle pollution.
  • AirData presents annual summaries of air pollution data from two EPA databases: the AQS (Air Quality System) database provides air monitoring data – ambient concentrations of criteria air pollutants at monitoring sites, primarily in cities and towns and the NEI (National Emission Inventory) database provides estimates of annual emissions of criteria and hazardous air pollutants from all types of sources.
  • The Air Quality Partnership of the Delaware Valley provides Ground Level Ozone and Particle Pollution Forecasts.
  • The National Air Toxics Assessment (NATA) is EPA’s ongoing comprehensive evaluation of air toxics in the U.S.
  • The EPA’s RadNet tracks fluctuations in gamma radiation emitted from airborne radioactive particles at Philadelphia’s LAB Monitoring Site.
