Rules Regarding the Use of Manure Storages for Septage Have Changed

By cptp | 2:58 PM, 09/23/2016

There have been some changes to the Administrative Codes regulating dairy farms.  As of September 1st ATCP 65 took effect which replaced ATCP 60 Dairy Farms and ATCP 80 Dairy Plants.  With that change, a number of regulations were changed to bring Wisconsin’s Administrative Code more in line with the Pasteurized Milk Ordinance.  Under the new rules,  ATCP 65.22(6)(c) does not allow the mixing of human septage and animal waste on any dairy farm regardless of whether they are Grade A or Grade B.

The previous rules allowed Grade B dairy farms to mix the wastes. Older NRCS and WI DNR policies also allowed up to 25,000 gallons of non-manure wastewater to be added to manure storage to aid agitation and pumping, but any storages built using the newer (2012 or after) USDA NRCS 313 standard, or in counties whose ordinances reference the newer standards, are not allowed to add non-dairy wastes to the lagoon. 

Grey waters (sinks, milking parlor washdowns, etc) are still allowed under ATCP, NRCS and DNR rules.  The only clarification under the current state code is that they cannot be added to the gutter in the milking barn or parlor.  They must be pumped/piped directly to the manure storage structure. 

The specific rule is as follows:

ATCP 65.22(6) Toilets.

(a) Every dairy farm shall have one or more sanitary toilets that are conveniently accessible by persons engaged in milking operations. A conveniently accessible toilet may include a toilet in a farm residence or other farm building.

(b) Toilets, under par. (a), shall comply with ch. SPS 362. Toilets shall be kept in clean and sanitary condition.

(c) There shall be no mixing or storage of human waste or septage with animal manure on a dairy farm.
