Risk & Resilience Assessments And ERPs

Questions Concerning New AWIA Requirements? We’ve got answers.

Community water systems that serve more than 3,300 people are required to complete a Risk and Resilience Assessment as well as develop an Emergency Response Plan (ERP) under Section 2013 of America’s Water Infrastructure Act (AWIA) of 2018.

What is a Risk and Resilience Assessment?

Risk and Resilience Assessments evaluate the vulnerabilities, threats, and consequences from potential hazards, including:

  • Natural hazards and malevolent acts
  • Resilience of water facility infrastructure
  • Monitoring practices
  • Financial systems
  • Chemical storage and handing
  • Operation and maintenance

With this new requirement, utilities must conduct the assessment and submit certification of its completion to the U.S. EPA by:

  • March 31, 2020 if serving >= 100k people
  • December 31, 2020 if serving 50k-99,999 people
  • June 30, 2021 if serving 3,301 to 49,999 people

When do water utilities need to get their Risk and Resilience Assessments re-certified?

Your utility must review the Risk and Resilience Assessment and submit a re-certification to the U.S. EPA every five years.

What is included in an ERP for drinking water utilities?

ERPs are critical for drinking water utilities as they provide plans and procedures for responding to a natural hazard or malevolent act that threatens safe drinking water. Preparing and practicing an ERP can save lives, prevent illness, enhance security, minimize property damage and lessen liability. Included in the plan are actions and identified equipment that are necessary to lessen the impact of a natural hazard, including alternative water sources and the relocation of intakes and flood protection barriers.

When do water utilities need to certify completion of their ERPs?

After completion of the risk and resiliency assessment, utilities must develop or update an Emergency Response Plan and certify completion to US EPA no later than six months after the risk and resiliency assessment certification.

When do water utilities need to get their ERPs re-certified?

Within six months of submitting the re-certification for the risk and resilience assessment, utilities must certify they have reviewed and, if necessary, revised, their emergency response plan.

Where can I find more information?

The U.S. EPA has a wealth of information on their website regarding these two new requirements. Use the links below to learn more.

T&H Receives Engineering Excellence Award

Tata & Howard, Inc. is pleased announce the Shrewsbury, MA Home Farm Water Treatment Plant as a Bronze winner for the 2020 American Council of Engineering Companies of Massachusetts’ (ACEC/MA) 2020 Engineering Excellence Award.

Tata & Howard evaluated various treatment options for design and construction of a water treatment facility based on loading rates, removal efficiencies, and estimated costs for removal of manganese. Manganese levels of the Home Farm Wells in Shrewsbury, MA had exceeded MassDEP’s Secondary Maximum Contaminant Level (SMCL) of 0.05 mg/L and the Office of Research and Standards Guidelines (ORSG) Lifetime Health Advisory limit of 0.3 mg/l. Based on the result of pilot testing, Tata & Howard, Inc. recommended biological pressure filtration for removal of iron and manganese.

Tata & Howard, Inc. provided lead engineering services for the design, permitting, funding assistance, bidding, award, construction administration, and resident project representation of a new 7.0 million gallons per day (mgd) Home Farm Water Treatment Plant to replace the existing treatment facility, which did not have processes to remove manganese.

The Water Treatment Plant focuses around biological pressure filtration processes for manganese removal using naturally occurring groundwater microorganisms with minimal chemical addition. Biological pressure filtration offers higher loading rates than conventional catalytic media for iron and manganese removal.

The Home Farm Water Treatment Plant is the largest biological pressure filtration facility in the northeast United States. The Home Farm Water Treatment Plant cost $14,900,000 inclusive of engineering and contingencies, of which approximately $1.2 million was for the biological filters.

Winning ACEC Engineering Excellence Award projects exemplify ingenuity and professionalism and represent the breadth of engineering’s contributions to our everyday lives. Projects display outstanding examples of how engineers connect communities, provide safe and reliable water and energy, and make buildings safe and efficient.
