NHDES is Now Accepting Applications for Culvert Flood Risk Assistance Grants

PORTSMOUTH, NH – The New Hampshire Department of Environmental Services (NHDES) is accepting Culvert Flood Risk Assistance Grant applications for the replacement of outdated, undersized, perched, and/or degraded culverts that are highly susceptible to flooding. The purpose of this funding opportunity is to encourage the replacement of high-risk culverts with better designed crossings that meet improved structural and environmental design standards and flood resiliency criteria. Incorporating these standards into culvert replacement designs will reduce flood hazards and risks to public safety, including culvert failure and road washout.

Eligible applicants include New Hampshire municipalities and non-governmental organizations. Total anticipated funding available for the Culvert Flood Risk Assistance Grant Program is approximately $1,000,000. Funds are made available to NHDES through the American Rescue Plan Act.  

Applicants may request a maximum of $400,000 per culvert replacement project. A portion of the grant award may be used to fund non-construction related activities, including engineering and design, permitting, bidding/construction contract services, and project management and reporting, up to a maximum of 20% of the grant award. A match commitment will not be requested for this grant program.

For instructions, evaluation criteria, and to access the application form, visit the Culvert Flood Risk Assistance Grant Program webpage. Applications must be submitted using the online application form no later than 4:00 PM ET on Friday, July 1, 2022.

Please contact NHDES Watershed Management Specialist Ben Sweeney at (603) 559-0021 or benjamin.r.sweeney1@des.nh.gov with inquiries about this funding opportunity.

2022 Pre-Applications Now Available for the Drinking Water State Revolving Loan Fund Program

Announcing the 2022 DWSRF Pre-Application Solicitation!  

The New Hampshire Department of Environmental Services (NHDES) is now accepting pre-applications for the 2022 Drinking Water State Revolving Fund (DWSRF) for drinking water infrastructure projects. Community public water systems and non-community/non-transient non-profit public water systems are eligible to apply for important water system projects such as replacing water mains, lead service lines inventory and replacement, new pump houses, developing new sources, rehabilitating tanks, treatment systems, or upgrading meters. The program includes principal forgiveness for eligible disadvantaged, year-round communities.

The Drinking Water and Groundwater Advisory Commission looks to fund projects that are determined to be “ready”.  A ready project is one that has exhausted non-DWGTF funding options.  The Commission recognizes the significant contribution to funding water system improvement projects by the DWSRF program.  Learning about the DWSRF program and the new funding sources for 2022 is important if a water system is intending to apply to the DWGTF in the fall.

The DWSRF Pre-application is available online at: 2022 DWSRF Pre-Application Form

Pre-application Deadline: June 1, 2022 (by midnight)

American Rescue Plan Act (ARPA)

Remaining grant funds from NHDES’ America’s Rescue Plan Act are available and will be combined with DWSRF offers as funding allows.

Bipartisan Infrastructure Law (BIL)

BIL is providing new funding in addition to the annual DWSRF allotment for the next five years. This supplemental funding will help water systems tackle lead and emerging contaminant issues. The new Lead Service Line (LSL) SRF and Emerging Contaminants (EC) SRF programs provide funding specifically for LSL inventory and replacement and efforts to address emerging contaminants with a focus on PFAS and Manganese. Costs for LSL and EC projects and/or components must be identified in the pre-application.

Plans for the new BIL funding programs are still being developed including eligibility for increased subsidy amounts so we strongly recommend you submit a pre-application for your drinking water infrastructure projects.

Check out the DWSRF Webpage for more information about the DWSRF program.

Release: NHDES is Now Accepting Applications for Critical Flood Risk Infrastructure Grants

PORTSMOUTH — The New Hampshire Department of Environmental Services (NHDES) Coastal Program and Watershed Assistance Section are accepting Critical Flood Risk Infrastructure Grant (CFRING) applications for flood resilience and stormwater management projects located within New Hampshire’s Coastal Watershed. Coastal watershed communities and their stormwater infrastructure are highly susceptible to damage from severe flood risks, including relative sea-level rise (RSLR), coastal storms, RSLR-induced groundwater rise, extreme precipitation, and freshwater flooding. According to the 2019-2020 New Hampshire Coastal Flood Risk Summary, these flood hazards are projected to intensify with the effects of climate change. Furthermore, many coastal watershed communities are subject to federal permits that require improved stormwater management. This new grant program intends to support planning and assessment work, as well as implementation projects that reduce flood risk and address stormwater management challenges.

For the purposes of CFRING, “flood resilience” refers to the capacity of a community or system to thrive in a changing climate – not only measured by the capacity to “bounce back” quickly from shocks and stresses like storms, but also measured by the capacity to “leap forward” to create new ways of working to achieve community goals and social, economic, and environmental well-being over the long-term. “Stormwater management” includes use of structural or nonstructural practices designed to reduce stormwater runoff pollutant loads, discharge volumes, and/or peak flow discharge rates.

Eligible applicants include municipalities, quasi-governmental organizations (e.g., regional planning commissions, county conservations districts, etc.), non-governmental organizations, and academic institutions. Projects must take place within one or more of New Hampshire’s 42 Coastal Watershed communities.[1] Total anticipated funding available for 2022 CFRING projects is approximately $4.5 million. Applicants may request a maximum of $100,000 per Planning and Assessment project or $2.5 million per Implementation project. A match commitment will not be requested for this grant program. Funds are made available to NHDES through the American Rescue Plan Act.  

For instructions, evaluation criteria, and to access the application form, visit the CFRING webpage. Applications must be submitted using the online application form no later than 4:00 PM ET on Friday, April 15, 2022. An informational webinar about the CFRING funding opportunity will take place on Monday, March 7, 2022 from 1:30-2:30 PM ET. Those interested must register for the webinar in advance. A recording of the webinar will be made available on the CFRING webpage for those who are unable to attend.

Please contact NHDES Watershed Management Specialist Ben Sweeney at (603) 559-0021 or benjamin.r.sweeney1@des.nh.gov with inquiries about this funding opportunity.

Environmental Review Webinar hosted by NHDES

Announcing a free environmental review webinar in February!

The New Hampshire Drinking Water State Revolving Fund (DWSRF) Program will be hosting a Drinking Water Infrastructure Environmental Review Webinar, February 18, 2022, 9:00 am – 12:00 pm.

Environmental Reviews are required for proposed drinking water infrastructure projects, funded by NH Department of Environmental Services (NHDES) administered programs, to ensure potential environmental and socio-economic impacts are considered, the public is informed, and the project meets federal, state, and local requirements. The webinar will provide an overview of the Environmental Review process and requirements for projects receiving funding assistance through the DWSRF, Drinking Water & Groundwater Trust Fund (DWGTF), PFAS Remediation Loan Fund (PFAS-RLF) and American Rescue Plan Act Fund (ARPA) Programs. Presentations will be given by the NHDES Drinking Water & Groundwater Bureau (DWGB), NH Division of Historical Resources (DHR), Natural Heritage Bureau (NHB) and NH Fish & Game (NH F&G).

The intended audience for the webinar includes current/future water infrastructure funding recipients, consultants/engineers, operators, and anyone interested in learning more about the Environmental Review process and regulatory requirements for water infrastructure projects.
