What's New

EPA finalizes modification to the 2017 Construction General Permit (CGP). The U.S. Environmental Protection Agency (EPA) finalized a modification to the National Pollutant Discharge Elimination System (NPDES) 2017 Construction General Permit (CGP), which covers eligible stormwater discharges from construction activities in areas where the EPA is the permitting authority. The final modified permit will take effect on June 27, 2019. More information.

Emission Standards for Composite Wood Products. EPA published a final rule to reduce exposure to formaldehyde emissions from certain wood products produced domestically or imported into the US. After March 22, 2019, composite wood products must be labeled as TSCA Title VI compliant. More information.

Respirable Crystalline Silica in Construction. The new OSHA construction industry standard applies to all occupational exposures to respirable crystalline silica in construction work and sets a new Permissible Exposure Limit (PEL) of 50 micrograms of respirable crystalline silica per cubic meter of air (50.0 µg/m3) as an 8-hour Time-Weighted Average (TWA). More information.

CICA SWPPP section changes. CICA has updated links to EPA SWPPP guidance documents that were changed to reflect the new 2017 Construction General Permit (CGP). Go to SWPPP page.

EPA Issues Final Construction General Permit to Reduce Stormwater Pollution
EPA has issued the final 2017 Construction General Permit (CGP), a permit that will continue to reduce pollution to the nation’s waterways by requiring controls for stormwater discharges from construction sites. Stormwater discharges during construction activities can contain sediment and other pollutants that harm aquatic ecosystems, increase drinking water treatment costs, and pollute waters that people use for fishing, swimming, and other recreational activities.

The 2017 CGP is similar to the 2012 CGP, it replaces and includes discharge limitations and requirements for self-inspections, corrective actions, staff training, and development of a Stormwater Pollution Prevention Plan. It also includes several new features such as requiring waste containers to have lids or cover when not in use or at the end of the business day, requiring controls to minimize exposure of building materials containing PCBs to precipitation and stormwater, and requiring large disturbances to be stabilized faster. The 2017 CGP will take effect February 17, 2017 and will last for five years. More information.

EPA Finalizes Nationwide Electronic Reporting Rule for Stormwater Permits. In September, 2015 the U.S. Environmental Protection Agency (EPA) finalized a nationwide rule that requires construction site operators to submit certain National Pollutant Discharge Elimination System (NPDES) stormwater permit documentation to their permitting authorities using an electronic reporting tool, instead of filing paper. The new rule requires states to share these data with EPA, along with government-administered inspection and enforcement results. You can find more information here.
