Each Dairy Plus Program project requesting funding must include at least one of the following project components that reduce methane emissions and nitrogen and salt surplus. Climate-smart practices eligible for federal funding under this grant are limited to certain Natural Resources Conservation Service-listed practices or those supported and quantified by the CARB Benefits Calculator Tool for AMMP and/or DDRDP.

1. Projects accompanying a new, in-progress, or previously completed Alternative Manure Management Program project:

a. Vermifiltration – this practice must be implemented in conjunction with an existing or a new primary mechanical separator.

b. Solid separation of manure solids through a weeping wall – the system must have a minimum of two cells.

c. Advanced solid-liquid separation assisted by flocculants and/or bead filters – this practice must be implemented in conjunction with an existing or a new primary mechanical separator.

d. Advanced solid-liquid separation through centrifuge – this practice must be implemented in conjunction with an existing or a new primary mechanical separator.

e. Primary practices above (a., b., c. or d.) AND subsurface drip irrigation (SDI) using liquid manure.

f. Primary practices above (a., b., c. or d.) AND aerated composting, as follows:
i. Composting in vessel (composting in an enclosed vessel, with forced aeration and continuous mixing);
ii. Composting in aerated static pile (composting in piles with forced aeration but no mixing);
iii. Composting in intensive windrows (with regular turning for mixing and aeration);
iv. Composting in passive windrows (with infrequent turning for mixing and aeration);
v. Composting in aerated vermifiltration system (solids separated by the vermifilter are also processed by worms within the vermifilter).

IMPORTANT: Previous AMMP recipients (i.e., from 2017 through 2023 AMMP) with a closed-out project or still in progress (not a closed-out grant agreement) are eligible to apply for the 2024 Dairy Plus Program. The proposed project must be for an advanced manure management practice addressing both GHG emissions and nitrogen and salt surplus specified in the list above. Any previous AMMP recipient may be eligible to apply regardless of the past practice type implemented, but for certain practices (i.e., compost bedded pack barn, conversion from flush to scrape, pasture-based management), the proposed advanced practice must address the portion of the herd not already covered by the in progress, or previous, AMMP project, as the manure handled by those systems should already be largely removed from a liquid waste stream. Note: If the applicant is proposing a Dairy Plus Program project for an in progress AMMP project (i.e., is still in an active grant term), they cannot make changes to the AMMP project unless they follow the regular modification request processes outlined by AMMP. The Dairy Plus Program project must be proposed and achievable in a way that does not require altering or changing the already funded and approved AMMP project scope of work.

2. Projects accompanying a new, in-progress, or previously completed Dairy Digester Research and Development Program project:

a. Post-digester vermifiltration – this practice must be implemented after the anaerobic digestion of manure.

b. Post-digester advanced solid-liquid separation assisted by flocculants and/or bead filters – this practice must be implemented after the anaerobic digestion of manure.

c. Practices above (a., or b.) AND subsurface drip irrigation (SDI) using liquid manure digestate.

IMPORTANT: New, in progress, or previously completed DDRDP projects applying for the 2024 Dairy Plus Program must incorporate a post-anaerobic digestion practice or technology for treating the digestate material that exits the dairy digester. Such practices or technologies cannot be implemented before the anaerobic digestion system. Previous DDRDP recipients (i.e., from 2015 through 2023 DDRDP) with a closed-out project or still in progress (not closed-out grant agreement) are eligible to apply for the 2024 Dairy Plus Program. Note: If the applicant is proposing a Dairy Plus Program project for an in progress DDRDP project (i.e., is still in an active grant term), they cannot make changes to the DDRDP project unless they follow the regular modification request processes outlined by DDRDP. The Dairy Plus Program project must be proposed and achievable in a way that does not require altering or changing the already funded and approved DDRDP project scope of work.
