Workforce Pilot

The Maine Jobs and Recovery Plan provides $5 million in American Rescue Plan Act funds to the Maine Department of Transportation to support local, regional, and state workforce transportation pilot projects, especially in rural areas. Administered by MaineDOT’s Bureau of Planning, the department’s Workforce Transportation Pilot program is a competitive grant program that provides funds to support other workforce transportation pilot projects around the state. Funds may be used for capital and operating costs, including program start-up costs.

The Bureau of Planning anticipates a $750,000 award cap; however, that award cap is subject to change based on need and volume of applications. MaineDOT reserves the right to negotiate project scope and deliverables prior to finalizing awards. There is no minimum or maximum number of awards. Projects will be selected based on merit and the availability of funding.

While there is no application deadline, applicants are encouraged to submit projects as soon as possible. The Bureau of Planning will accept, evaluate, and make decisions on grant applications on an ongoing, rolling basis until all funds have been disbursed. In its evaluation process and awarding of funds, MaineDOT will consider that some applicants will be able to apply for funds sooner than others. In general, awarded projects should begin within four months of contract execution. This requirement can be waived based on circumstances as described by the applicant.

While projects may support transportation of workers from rural areas to more urban areas or centers of employment, the focus is on workforce transportation in rural areas. As such, some funds will be targeted specifically to connecting workers in rural areas to employment opportunities in rural areas.

Federal guidance provides that funds may be used to respond to COVID-19’s negative economic impacts on the tourism, travel, and hospitality industries. Other identified industries suffering comparable economic impacts include healthcare and social assistance; construction, trade, and logistics; manufacturing; education; agriculture, fishing, and forestry; information; and clean energy. Applicants must demonstrate that they are addressing challenges in these industries. Proposed initiatives must focus on workers and potential workers in these key industry sectors. MaineDOT staff will work with potential applicants to ensure that any proposals meet these requirements.

Applications may be submitted by employers or groups of employers, municipalities, non-profit organizations, human service organizations, and public/private transportation providers. Applicants are encouraged to engage with potential partners including, but not limited to, regional planning organizations, chambers of commerce and other business groups, county governments, workforce boards, and community action programs.

About MNRCP

The Maine Natural Resource Conservation Program (MNRCP) awards competitive grants to projects that restore, enhance, and protect high priority aquatic resources throughout Maine. MNRCP is administered by The Nature Conservancy on behalf of the Maine Department of Environmental Protection (DEP) and the U.S. Army Corps of Engineers. Since its launch in 2008, MNRCP has awarded over $36 million to non-profit groups, municipalities, and public agencies to help restore, enhance, or preserve wetlands and other important habitats at over 180 project sites across the state.

MNRCP was created to manage the allocation of funds collected through Maine’s In Lieu Fee Compensation Program. This voluntary program provides flexibility for regulators as well as for those seeking natural resource permits to choose a fee in lieu of more traditional permittee-responsible mitigation options. These so-called In Lieu Fees are collected by the Maine DEP and then transferred to the Natural Resource Conservation Fund administered by The Nature Conservancy.

Funds are awarded through an annual competitive grants process. Proposals are solicited each year and evaluated by a Review Committee, convened by the Maine DEP, and made up of public and nonprofit entities. Final award decisions are made in November or December of each year by the Interagency Review Team (Approval Committee) comprised of state and federal agencies. The Nature Conservancy administers the process but does not decide which proposals receive funding.

Apply

MNRCP awards competitive grants each year to projects that restore, enhance, and protect high priority aquatic resources in Maine. MNRCP funding rounds are usually announced in April or May. Public agencies, non-profit conservation organizations, tribes, and municipalities are encouraged to submit a Letter of Intent for eligible projects.
