Only Rain in the Storm Drain


 
Did you know that Flagstaff's storm drain system and sewer system are separate? What goes down the storm drain is not treated at a treatment plant, but flows untreated into the Rio de Flag. Help us protect our local waterways by preventing stormwater pollution. Hazardous Household Waste, including automobile oil, can be disposed of at the Flagstaff Hazardous Products Center (HPC).


Enjoy this video and remember: Only Rain in the Storm Drain!

Small Municipal Separate Storm Sewer System General Permit

 
 
ADEQ recently issued a new small Municipal Separate Storm Sewer System (MS4) permit, effective September 30, 2016. To view the new Stormwater Management Plan, click here.  
 
This permit is for certain public entities that operate municipal separate storm sewer systems. The permit authorizes the discharge of stormwater to U.S. waters from Small MS4s, which may include a city, town or county located fully or partially within an urbanized area as determined by the latest Decennial Census by the Bureau of Census; state, federal and other publicly-owned properties that discharge stormwater; and other areas designated by ADEQ. The permit requires the development of a stormwater management program. The permittees are required to follow six minimum control measures that must be built into their program including: Public Education and Outreach; Public Involvement and Participation; Illicit Discharge Detection and Elimination (IDDE) Program; Construction Site Stormwater Runoff Control; Post-Construction Stormwater Management; and Pollution Prevention and Good Housekeeping.
 
The City of Flagstaff requested coverage under the 2016 MS4 by submitting a Notice of Intent (NOI) to ADEQ.  ADEQ posted a public notice and proposes to issue Water Quality (AZPDES) Small MS4 General Permit (AZG2016-002) coverage to the City of Flagstaff. The City of Flagstaff is subject to provisions of the Federal Clean Water Act and the requirements of the Arizona Pollutant Discharge Elimination System (AZPDES) program, pursuant to Arizona Revised Statutes (A.R.S) Title 49, Chapter 2, Article 3.1, and Arizona Administrative Code (A.A.C.) Title 18, Article 9.

The City of Flagstaff encourages residents to view the small MS4 general permit and the NOI. Public comments are due to ADEQ by Email or mail (must be postmarked or received) by May 20, 2017. A link to the public notice on ADEQ's webpage is

Stormwater Credit Manual (click here)

The City of Flagstaff has revised the Stormwater Credit Manual.  The Manual is a document which provides for discounts on your stormwater billing (as shown on your water bill) for certain stormwater controls such as detention basins, Low Impact Development (LID) facilities and Rainwater Harvesting.  Many developments that have occurred since 1990 may be eligible for a discount.  The discount may be applied to commercial, industrial or residential developments.  As part of the application process, you will need to attest that the facility(s) are maintained on a regular basis by yourself or perhaps by a Homeowner's Association.  If you believe you or the subdivision you live in, may have a stormwater facility that may apply, you are encouraged to apply for a discount.
