Tighe & Bond’s Environmental Team Provides Support to Providence Water
Tighe & Bond has been providing on-call engineering services for Providence Water since 2016. The firm’s environmental team provides project support to Providence Water as part of various design projects. The Woonasquatucket River Crossing Project included borings and soil screening conducted in the project area to determine soil characteristics, install monitoring wells, and test the soils for potential contaminants. The project also involved coordination and approvals from the City of Providence Department of Public Works, Rhode Island Department of Transportation (RIDOT), Coastal Resources Management Council (CRMC), Rhode Island Department of Environmental Management (RIDEM), and the US Army Corps of Engineers. Tighe & Bond assisted with coordinating a pre-application meeting with the various agencies involved and prepared the necessary submittals required for each permit. The Atwood Avenue Water Main Project also included geotechnical and soil conditions evaluations along with the proposed new water main route to identify potential contamination issues.
Tighe & Bond provided regulatory compliance assistance at the Philip J. Holton WTP regarding Risk Management Program support related to gaseous chlorine storage. The tasks associated with this effort included:
- The development of a Process Hazard Analysis (PHA).
- Revisions to the existing facility Risk Management Plan (RMP).
- Submission of the RMP update and updates to the facility’s Emergency Action Plan (EAP).
The PHA systematically analyzes potential process failures and determines if additional controls are needed to prevent these failures from occurring. The revisions to the RMP were necessary to ensure that the most up-to-date site-specific and equipment-specific processes are documented based on EPA’s Program Level 3 standards. The RMP was developed for submission through the web-based portal called RMP*eSubmit.
Tighe & Bond has also provided water treatment engineering services primarily focused on the Philip J. Holton Water Treatment Plant and Providence Water’s extensive distribution system. The projects associated with the water treatment plant include a preliminary evaluation of options to provide redundancy to the existing 90-inch plant influent conduit from the Gainer Dam to the WTP and design and construction services associated with the rehabilitation and lining of the WTP settled water influent conduit.
