Employees in the Department's Bureau of Environmental Programs administer several state and federal programs regarding the protection of various aspects of our environment. Staff of the nursery inspection program work to control plant pests, diseases, and noxious weeds through nursery grower, nursery stock dealer, and greenhouse inspection and certification programs. Plant pest and disease quarantine programs are also regulated and administered by bureau staff members. The nursery inspection staff also inspects and certifies plant and plant products for domestic and international export. The Department also registers pesticides; tests, certifies and licenses pesticide applicators; and investigate alleged cases of pesticide misuse. The Bureau also operates a statewide agricultural pesticide container-recycling program and operates a pesticide laboratory that tests groundwater, soil, and plant samples for pesticide residues and ensures accurate marketing and labeling of pesticides. Another key program administered by Bureau staff involves the enforcement of proper storage, containment, and disposal of pesticides and fertilizers. The Department also administers the Livestock Management Facilities Act that regulates the siting and construction of livestock production facilities across the state and includes requirements regarding facility setback distances, facility design and construction standards, waste management plans, and livestock manager certification.
