Each Dairy Plus Program project requesting funding must include at least one of the following project components that reduce methane emissions and nutrient 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 2023 or previous 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. Practices above (a., b., or c.) AND subsurface drip irrigation (SDI) using liquid manure.

e. Practices above (a., b., or c.) 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 2022 AMMP) with a closed-out, completed, and operational project are eligible to apply for the 2023 Dairy Plus Program. The proposed project must be for an advanced manure management practice addressing both GHG emissions and nutrient 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 be addressing the portion of the herd not already covered by the previous AMMP project, as the manure handled by those systems should already be largely removed from a liquid waste stream.

 

2. Projects accompanying a new 2023 or previous 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 or previous DDRDP projects applying for the 2023 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 must not be implemented before the anaerobic digestion system. Previous DDRDP recipients (i.e., from 2015 through 2022 DDRDP) with a closed-out, completed, and operational project are eligible to apply for the 2023 Dairy Plus Program.
