(check if yes and summarize below) INSPECTION OVERVIEW AND FACILITY DESCRIPTION The EPA Inspection Team, along with representatives from the Maryland Department of Environment (MDE) conducted an inspection of Amen Corner Farm on May 3, 2024. The intent of the inspection was to observe the farm's compliance with their NPDES Concentrated Animal Feeding Operation (CAFO) General Permit No. MDG010285 (hereinafter, the "Permit"). During the inspection, the EPA Inspection Team asked questions pertaining to other farms that have coverage under the same permit. Jason Lambertson (hereinafter, "Lambertson Farm") is the permittee for the Permit. Lambertson Farm is a poultry operation consisting of five farms all operated by Jason Lambertson in Worcester County, Maryland. Four of the five farms under the CAFO Permit are pullet operations and the fifth farm (Pure Country Farm) is a broiler operation. According to the Notice of Intent (NOI) which was received by MDE on August 18, 2020, the operations are: Amen Corner Farm - 53,333 pullets (per flock) and 4 houses; Diane Lambertson Farm - 5,000 pullets (per flock) and 3 houses; 1. Millennium Farm - 53,333 pullets (per flock) and 4 houses; 2. Raven Farm - 53,333 pullets (per flock) and 4 houses; and Pure Country Farm, which is a broiler operation has 148,000 birds (per flock) in 4 houses. Lambertson Farm has a 2023 nutrient management plan (NMP) (Attachment A) dated October 19, 2023, and a comprehensive nutrient management plan (CNMP) (Attachment B) dated October 2020. The NMP states that Diane Lambertson Farm has 19,000 pullets per flock. The NMP also shows Raven Farm and Millennium Farm each now having 2 poultry houses. The pullet operations have 2 flocks per year with each flock having a 21-week residency. The broiler operation has 5 flocks per Unique Project #: ECAD-5452 Lambertson Farm (MDG010285) year. A separate litter shed (poultry waste storage structure (PWSS)) is provided for each farm and according to the table on Page 6 of the CNMP their capacities are: 1. Amen Corner Farm - 40' x 124` with a storage capacity of 24,800 cubic feet (cu.ft.) 2. Diane Lambertson Farm - 40' by 60' with a storage capacity of 12,000 cu.ft. 3. Millennium Farm - 40' x 116' with a storage capacity of 23,200 cu.ft. 4. Raven Farm - 40' x 88' with a storage capacity of 17,600 cu.ft. 5. Pure Country Farm - 40' x 184' with a storage capacity of 36,800 cu.ft. The storage capacities were changed slightly for two of the PWSSs in the NMP. According to the NMP, the PWSS for Pure Country Farm is now 50' x 188' with a capacity of 47,000 cu.ft. and Amen Corner Farm's PWSS is 40' x 120' with a capacity of 24,000 cu.ft. Litter is windrowed after each flock and according to the NOI crust outs are conducted on a "once a year on as needed basis". The crust outs are conducted by a separate company named Ellis Farms Inc. ("Ellis"), a manure broker located in Delaware. Ellis conducts the cake outs and cleanouts for Lambertson Farm and either takes the litter directly to their Delaware facility or stores it within the onsite litter sheds/PWSS to retrieve later. Based on conversations with Mr. Lambertson, pullet litter is low in nutrients and therefore needs to be blended with other litter for land application. Lambertson Farm is permitted as a "No-Land" operation. Therefore, the facility's NMP and CNMP do not have information pertaining to the land application of poultry litter/manure. All land owned by Lambertson Farm that is farmed is leased out to Twin Oak Farms. There is a total of 54-acres leased. The owner/operator of Twin Oak Farms (Mr. Wayne Lambertson) is a relative of the owner/operator of the Lambertson Farm (Mr. Jason Lambertson), and the two operations share an office. Twin Oak Farms receives poultry litter/manure from Ellis to land apply on the 54acres leased from Lambertson Farm. Twin Oak Farms applies poultry litter/manure to land it leases from Mr. Lambertson at the Diane Lambertson Farm, Millennium Farm, Raven Farm, and Pure Country Farm. Poultry litter/manure is not land-applied at Amen Corner Farm due to high phosphorous levels (although it does receive inorganic materials). Therefore, poultry litter/manure generated by poultry houses at Lambertson Farm is removed by Ellis, and poultry litter/manure from Ellis is brought back and land-applied on the 54-acres of cropland owned by Lambertson Farm. Pullet mortalities at Amen Corner Farm are composted within a 24' channel composter which is attached to Pure Country's PWSS. The NMP shows in the Amen Corner Farm "Quantity of Poultry Litter, Cake/Crust Available per Year" Table that Amen Corner Farm would not be exporting litter from 2022 through 2026. Similar information is contained in the tables for each of the pullet operations within the NMP. The Annual Reports for 2021, 2022 and 2023 show hundreds of tons of litter being exported from the farms but do not have a specific amount for each farm. According to the tables in the NMP, only 30 tons of litter/manure should have been exported each of these years. The inspection was supposed to occur between flocks which is an approach the Maryland Department of Environment (MDE) has been implementing to reduce the spread and risk of avian influenza (AI). At the time of the inspection the integrator did not pick up the pullet flock from Amen Corner and there were birds at the farm. EPA and MDE decided not to walk the farm at the Unique Project #: ECAD-5452 Lambertson Farm (MDG010285) time of the inspection and allowed the farm owner operator to take photos of the houses and litter shed at Amen Corner Farm. SUMMARY OF OBSERVATIONS The following observations have been identified relative to the requirements of NPDES Concentrated Animal Feeding Operation (CAFO) General Permit No. MDG010285. Permit Requirement: Part II.B of the permit defines "Animal Waste" as "liquid and/or solid waste from animal feeding, milking, holding or other animal operations. Animal waste includes all manure, poultry litter, offal and process wastewater." Part II.P of the permit defines Land Application Area as "Land under the control of an AFO owner or operator, whether it is owned, rented or leaded to which manure, litter, or process wastewater from the production area is or may be applied." Part IV.F.1.d.i. defines No-land operations as that shall "..not apply manure, litter or process wastewater from any source to fields under control of the operator. Manure, litter, or process wastewater generated by the AFO shall be exported to an operation that is not under control of the operator of the permitted AFO;" Observation 1 Poultry manure/litter generated by the CAFO and is removed by Ellis, a manure broker in Delaware. Twin Oak Farms land-applies poultry manure/litter from Ellis to the fields owned by the CAFO at Raven Farm, Diane Lambertson Farm, Pure Country Farm, and Millennium Farms. Permit Requirement: Part III.B.2 of the permit states "To obtain coverage under the General Discharge Permit, and maintain compliance thereunder, all portions of the Required Plan must be current or unexpired at the time of the NOI submission, may be required to be updated if not current during application processing by the department, and must remain current or unexpired throughout the duration of General Discharge Permit coverage, Subsequent updates of the NMP portion of the Required Plan may be accomplished through a separate NMP document." Observation 2 The 2023 NMP for all the farms shows a total of 30 tons of litter being removed from the operation in total. The Annual Reports for 2022 and 2023 appear to show a few Unique Project #: ECAD-5452 Lambertson Farm (MDG010285) hundred tons of litter being removed each of the years. Documents from Amen Corner Farm show 624 tons of litter exported to Ellis from Amen Corner Farm in 2023. Permit Requirement: Part IV.A.6.b.ii of the permit requires that "No-Land" operations document the test methods used to sample and analyze manure, litter, and process wastewater. Observation 3 The Inspection Team was provided with documentation on the litter analysis results which was shared with operations that took the litter. However, the Inspection Team was unable to find in the NMP, CNMP or within the litter analysis the test method used for analysis (Attachment C). Permit Requirement Part IV.A.6.c. of the permit requires that "No-Land" operations document "Mortality disposal including date, number of animals and method of disposal.". Observation 4 The Inspection Team was provided with documentation on the total number of mortalities at Amen Corner Farm and the NMP and CNMP stated that all mortalities were composted, and the farmer confirmed this. However, based on correspondence with the farmer, it appeared the mortality information was being housed by the integrator and provided to the farm at their request.
