When preparing your budget, note that the 40% minimum match requirement now accepts any non-federal funds rather than just local sources. To assist with your proposal development, new mapping applications and TMDL resources have been added to the external links. Additionally, please direct any technical or general inquiries to the main NPS Grants email, as the specific contact for pollutant load reductions has been removed.
