Mr. John Doyle Messer Pond Protective Association PO Box 103 New London, NH 03257

Dear John;

Congratulations! The New Hampshire State Conservation Committee has awarded a 2020 Conservation License Plate grant to the Messer Pond Protective Association for the Messer Pond Watershed Plan -Phase 2 County/Fieldstone Runoff Mitigation project. The SCC 2020 grant award amount is $10,900.00.

Grant award conditions include the following: Engineering designs should meet Best Management Practices and Department of Environmental Services storm water standards. The Department of Environmental Services will review design plans prior to implementation.

Over the next few months I will be working with the lead contact person ( as. identified in the grant application) to complete a Grant Agreement contract with the Department of Agriculture, Markets and Foods on behalf of the New Hampshire State Conservation Committee. Unless notified otherwise, I will be sending the contact person via email the required documentation. This grant will require approval from the Governor and Executive Council. The targeted date to complete the Grant Agreement approval process is May 2020. Please note that funds are not officially awarded until the Grant Agreement is fully executed by all parties.

Again, congratulations on the award. Please contact me at 603.868.6112 or bluesky24@comcast.net should you have any questions.

Sincerely,
