Biosolids Land Application 5, Pathogen and Vector Attraction Reduction 5.3 The minimum duration between application and harvest,grazing or public access to areas where Class B. biosolids have been applied to the land is as follows: a. 14 months for food crops whose harvested parts may touch the soil./biosolids mixture(such as melons, squash,tomatoes,etc.),when biosolids are surface applied,incorporated or injected. b. 20 months or 38 months depending on the application method for food crops whose harvested parts grow in the soil(such as potatoes,carrots,onions,etc.). The 20 month time period is required when biosolids are surface applied or surface applied and incorporated after they have been on the soil surface for at least four(4) months. The 38 month time period is required when the biosolids are injected or surface applied and incorporated within four(4)months of application. c. 30 days for feed crops,other food crops(such as field corn,sweet corn,etc.),hay or fiber crops when biosolids are surface applied,incorporated or injected. d. 30 days for grazing of animals when biosolids are surface applied,incorporated or injected. e. One year where there is a high potential for public contact with the site,(such as a reclamation site located in populated areas,a construction site located in a city,turf farms,plant nurseries, etc.)and 30 days where there is low potential for public contact(such as agricultural land,forest,a reclamation site located in an unpopulated area,etc.,)when biosolids are surface applied,incorporated,or injected. 6. Management Practices 6.1 The management practices for the land application of biosolids are described in detail in Minnesota Rules,pt. 7041.1200 and must be followed lmless specified otherwise in a site approval letter or a permit issued by the MPCA. 6.2 Overall management requirements: a.

Biosolids shall not be applied within 33 feet of a wetland or waters of the state unless specified otherwise by the 1vIPCA in a permit. 7. Monitoring Requirements 7.1 Representative samples of biosolids applied to the land must be analyzed by methods specified in Minnesota Rule pt. 7041.3200 for the following parameters: arsenic,cadmium,copper,lead,mercury,molybdenum, nickel, selenium,zinc,Kjeldahl nitrogen,ammonia.nitrogen,total solids,volatile solids,phosphorus,potassium and pH.
