MS4 Compliance in Arizona


UtiliSync is a GIS-based software platform that automates the entire documentation process; from generating forms, to completing records and distributing and archiving those records. Watch this video to see how it works.

Why Documentation?

The revised General Permit for Small MS4s in Arizona became effective September 30, 2016. As a Small MS4, you are required to perform certain activities and to document those activities. If you do not, you could face large fines from the State and EPA. Just ask Salt Lake County, Utah, how serious the EPA is regarding documentation. They were hit with a $280,000 fine for not having the proper documentation in place during an audit.

Documentation Requirements

In general, MS4s operating under the Small MS4 General Permit are required to keep all records required by the permit for a minimum period of three years (Part 8.2), including:

  • Monitoring results
  • Copies of reports
  • Records of Screening
  • Follow-up and elimination of illicit discharges
  • Maintenance records
  • Inspection records
  • Enforcement actions
  • Data used in the development of the NOI, SWMP, plans and annual reports

Monitoring Records

Records of monitoring information must include, at a minimum:

  • Date
  • Exact place
  • Time of monitoring event
  • Individuals who performed the analyses
  • Analytical techniques or methods used
  • Results

The monitoring results need to be submitted to the State in a Discharge Monitoring Report (Part 8.3).

Annual Report

A summary report needs to be submitted annually. The purpose of the report is to document and summarize implementation of the SWMP during the previous year and evaluate program results. UtiliSync can be used to track activities that are included in the report, such as:

  • IDDE: Number of illicit discharges detected, responded to, eliminated, and enforcement actions taken.
  • Construction site Stormwater Runoff Control: Inventory, number of sites visited, and enforcement actions taken.
  • Post-Construction: Number of enforcement actions and site visits conducted.
  • Pollution Prevention and Good Housekeeping for Municipal Operations: Inventory of municipal facilities and stormwater inspections for each facility.
