Signs of all shapes, sizes, colors, and purposes can be found throughout any construction site. Which one do you need? What information is required? Does it have to be a specific size or color? There are many things to take into consideration but always refer to any local regulations that you will be obtaining permits for.
If you happen to be under the jurisdiction of the Environmental Protection Agency (EPA) Construction General Permit (CGP), you must post a sign or other notice of your permit at a safe, location near the construction site. At a minimum, the notice must include: permit number, a contact name and phone number, the Uniform Resource Locator (URL) for the SWPPP (if available), or the following statement: “If you would like to obtain a copy of the Stormwater Pollution Prevention Plan (SWPPP) for this site, contact the EPA Regional Office at [include the appropriate CGP Regional Office]” and the following statement “If you observe indicators of stormwater pollutants in the discharge or in the receiving waterbody, contact the EPA through the following website: https://www.epa.gov/enforcement/report-environmental-violations.”
Several states have their own CGP to regulate construction activity. For example, in the newly adopted CGP in Arizona implemented in 2020, the new requirement is that the operator posts their authorization number(s) near the main entrance. There are specifics about some items that must be posted as well such as the phrase “For stormwater complaints, please visit www.azdeq.gov.” in 2” or greater lettering.
These are just a few examples pertaining to Stormwater. Many states, counties, cities, and other municipalities have their own requirements for site posting, such as dust-generating operations in Maricopa County, or noise ordinance in the city of Phoenix. Always check with your local municipalities or consult Earthworks to ensure that you are in compliance with any posting requirement.
