“Agricultural employer” means any person, corporation, association, or other legal entity that:

C. Recruits and supervises employees or is responsible for the management and condition of an agricultural establishment.
“Agricultural establishment” is a business operation that uses paid employees in agricultural operations.
“Agricultural operation” means any operation necessary to farming pursuant to Section 3437.
“Hand-labor operations” means agricultural activities or agricultural operations performed by hand or with hand tools in the production of food, fiber, or other materials such as seed, seedlings, plants, or parts of plants. “Hand-labor operations” also include other activities or operations performed in conjunction with hand-labor in the field. Some examples of “hand-labor operations” are the hand-manipulation of irrigation pipes and other irrigation equipment by irrigators; the hand-cultivation, hand-weeding, hand-planting and hand-harvesting of vegetables, nuts, fruits, seedlings or other crops, including mushrooms; and the hand packing of produce into containers, whether done on the ground, on a moving machine or in a temporary packing shed located in the field. “Hand-labor” does not include such activities as logging operations, the care or feeding of livestock, or hand-labor operations in permanent structures (e.g., canning facilities or packing houses).
“Handwashing facility” means a facility providing either a basin, container, or outlet with an adequate supply of potable water, soap or other suitable cleansing agent and single-use towels.
“Potable water” means water that meets the primary standards for drinking purposes found in Title 22, California Code of Regulations, Division 4, Chapter 15.
“Single-user toilet facility” means a toilet facility with a locking mechanism, controlled by the user, with one toilet, or one toilet and one urinal.
“Toilet facility” means a fixed or portable facility designed for the purpose of adequate collection and containment of the products of both defecation and urination which is supplied with toilet paper adequate to employee needs. Toilet facility includes biological, chemical, flush and combustion toilets and sanitary privies, in portable or mixed form.
