Original Notice.

Preproposal statement of inquiry was filed as WSR 99-15-107 on July 21, 1999.

Title of Rule: Safety standards for agriculture, chapter 296-307 WAC, Temporary labor camps, WAC 296-307-161 Temporary worker housing (Part L) and 296-307-163 Cherry harvest camps (Part L1).

Purpose: The 1999 legislature passed ESSB 5599 (chapter 374, Laws of 1999) requiring the Department of Labor and Industries (L&I) and the Department of Health (DOH) to adopt joint rules for the licensing, operation, and inspection of temporary worker housing and the enforcement of these rules. ESSB 5599 also removes temporary worker housing responsibilities from the State Board of Health and directs the agencies to establish standards for cherry harvest camps. Cherry harvest standards may include some variation from standards that are necessary for longer occupancies, provided they are as effective as the standards adopted by WISHA.

Beginning in June 1999 an L&I/DOH joint project team with OSHA representation has been meeting regularly and has developed the proposed wording for the temporary worker housing rule and the cherry harvest rule. During the development of the wording, the joint project team met twice with grower and worker advocates and a third time with the advocates and the public to gather their input. Using the Washington Interactive Television, one public hearing will be held simultaneously in four locations (Wenatchee, Yakima, Tri-Cities, and Mount Vernon) on January 6, 2000. The current WAC 296-307-160 Temporary labor camps is being repealed in its entirety and reissued under WAC 296-307-161 Temporary worker housing and 296-307-163 Cherry harvest camps to improve usability and clarity. Current Department of Health requirements have been incorporated into the temporary worker housing and cherry harvest camps rules.

Rule is not necessitated by federal law, federal or state court decision.

Explanation of Rule, its Purpose, and Anticipated Effects: See Purpose above.

Proposal Changes the Following Existing Rules: See Purpose above.

A small business economic impact statement has been prepared under chapter 19.85 RCW.

The Department of Health (DOH) adopted and then revised regulations governing the provisions of temporary worker housing by cherry orchard operators in 1996, 1997 and 1998. These regulations had to meet the requirements of the enabling statute: "[t]he department shall adopt by rule a temporary worker building code in conformance with the temporary worker housing standards developed under the Washington industrial safety and health act, chapter 49.17 RCW" (RCW 70.114A.081(1)). The Department of Labor and Industries (L&I) and the federal Department of Labor, upon reviewing the regulations, concluded that they did not conform to the Washington Industrial Safety and Health Act (WISHA). The questions about the legality of the temporary worker housing regulations and other concerns prompted the legislature in 1999 to adopt ESB 5599 directing that "[t]he department of health and the department of labor and industries shall adopt joint rules for the licensing, operation and inspection of temporary worker housing and the enforcement thereof. These rules shall establish standards that are at least as effective as the standards developed under the Washington industrial safety and health act, chapter 49.17 RCW."

Because employers are not required to supply their employees with housing, regulating the housing supplied by orchard operators presents a dilemma for L&I and the DOH. On the one hand many grower-supplied housing sites are often dismal. On the other hand, designing temporary worker housing regulations that are stringent will substantially raise the cost of providing temporary worker housing and cause some orchard owners to close their camps. With only 25 of 290 growers providing temporary housing in 1998, sheltering 1,765 of approximately 16,000 cherry orchard migrant workers, the prospect of losing a significant number of beds had to be considered during rule development. The objective of L&I (here after referred to as the department) was to maximize worker health and safety, while conforming to federally mandated requirements.

Need for a Small Business Economic Impact Statement: The Regulatory Fairness Act (RFA), chapter 19.85 RCW, requires that the economic impact of proposed regulations or amendments on small businesses must be examined relative to their impact on large businesses. The RFA outlines the requirements for a small business economic impact statement (SBEIS). For the purposes of an SBEIS the term small business is defined as a business entity that has the purpose of making a profit and has fifty or fewer employees. The agency must prepare an SBEIS when a proposed rule, or rule amendments, have the potential of placing a more than minor economic impact on business. For the businesses considered (SIC 017: Fruits and tree nuts), the minor impact threshold is 50 (1990 dollars) per business. These values are calculated as 0.1% of profits for a business of 50 employees (Guide for Facilitating Regulatory Fairness, 1993). The estimated business (establishment) compliance costs, presented in Table 3 below, reveal that the costs created by the proposed changes to chapter 296-307 WAC will exceed the SBEIS minor cost threshold. Therefore an SBEIS is necessary.

Estimating the Compliance Costs for the Proposed Amendments: To estimate the rule compliance costs and determine if there is a disproportionate impact on small businesses, the department examined costs for a hypothetical small orchard camp with beds and shelter for 30 workers. The estimated small camp costs were compared with the estimated compliance costs for a hypothetical large camp with facilities for 90 workers. Compliance costs are presented on a per employee and on a per establishment basis. Costs were estimated for the following individual rule requirements.

Table 1: Rule Requirements for Small and Large Camps

Requirement	Small Camp: 30 workers	Large Camp: 90 workers
Grower-supplied housinga	5 tents (6 workers per tent)	15 tents
Electrical outletsb	1 per tent	same
Lighting in tentsc	3 100 watt, 1 75 watt light fixtures per tent	same
Bedsd	Option 1: 30 cots, 1 per worker Option 2: 15 bunk beds, 1 per 2 workers	Option 1: 90 cots, 1 per worker Option 2: 45 bunk beds, 1 per 2 workers
Flooringe	Option 1: Synthetic material Option 2: Concrete slab	same
Enhanced cooking facilitiesf	Option 1: Central cooking Option 2: In-tent cooking	same
Refrigeration: 2 cubic feet/workerg	Option 1: Central cooking, enlarged facility Option 2: In-tent cooking, no enlargement necessary	same
Water testingh	Site/well inspection and test	same

Estimated per employee cost for compliance with the proposed rule is shown in Table 2 below for large and small camps, under Options 1 and 2.

Table 2: Estimated annual per occupant compliance costs

Rule Requirement	Option 1		Option 2
Camp size--->	30	90	30	90
Grower supplied housing	$47.43	$42.48	$47.43	$42.48
Tent electrical outlets	$23.60	$23.60	$23.60	$23.60
Tent lighting	$5.81	$5.81	$5.81	$5.81
Beds	$8.53	$8.53	$17.34	$17.34
Tent flooring	$4.00	$4.00	$6.37	$6.37
Enhanced cooking facilitities	$0.95	$0.63	$47.38	$47.38
Increased refrig. space	$5.11	$4.53	$1.45	$1.45
Water testing	$3.67	$1.22	$3.67	$1.22
Total Costs	$99.10	$90.80	$153.06	$145.65

The per employee compliance costs are approximately 7% higher for small camp operators; Option 1, small camp $99.10 versus $90.80 for large camp for a difference of 9%; Option 2, small camp $145.65 versus $153.06 for large camp for a difference of 5%. The department believes that this small difference is not indicative of a disproportionate impact on small business entities (small camp operators). Table 3 presents the per establishment costs for large and small camps, under Options 1 and 2.

Conclusions: Using a variety of sources, the compliance costs for the proposed amendments to the rules pertaining to housing camps for cherry harvest agricultural workers (WAC 296-307-161 through 296-307-163) were determined. The estimated new costs per establishment, presented in Table 3, indicate the proposal will have a more than a minor impact on large and small camp operators. A comparison of per employee compliance costs for operators of large and small cherry orchard work camps, see Table 2, indicates that they will be 5 to 9% higher for small camp operators. This cost difference is not substantial and therefore it is my conclusion that the proposal will not have a disproportionate impact on small business.

Table 1 Notes

a	Assumptions for grower-supplied housing: 1. Operators will meet the shelter requirements by utilizing the North Central Community Action Council's tent rental program. Cost to growers of $160 ($125 for depreciated cost and $35 for annual storage; tents used two times a year) to rent a tent for 21 days. 2. Growers must pay for approximately 8 hours of labor (tent set up, break down, maintenance, and storage) for each tent. At a wage rate of $10 hour this adds $80 to the cost of each tent. 3. Growers must also pay transportation costs for four round trips per year (site survey, delivery of tent, set up of tent, break down of tent). At an average round trip of 180 miles and costs $0.31 per mile, transportation adds $223 to the cost of tents. 4. Total costs: A small operator is estimated to face annual tent rental costs of about $1423 while large growers costs approximate $3823.
b	Assumptions for electrical outlets: 1. The rule would require a convenience outlet in every tent. The camp operators would need to install 50 ft. of underground wiring for each tent. A GFI outlet mounted on a 4x4 pressure treated post (set in concrete), 15 ft. away from the underground wiring will supply the electricity. The underground wiring costs $1.00 per foot, the 4x4 post $6.39, the concrete $5.55 (3 cubic feet), GFI outlet $12.97, and 4 hours of labor at $60 per hour. Total cost of the exterior wiring assembly is approximately $325 per tent. Discounting this amount at a 7% interest rate over 20 years results in an annual cost of $30.67 per tent. 2. To bring the electricity inside the tent will require six feet of flexible conduit ($1.10 per foot), and two duplex outlets ($1.50 per item), and one hour of labor to assemble-total cost $69.60. Discounting this amount at a 7% interest rate over seven years results in an annual cost of about $12.91 per tent. 3. The analysis also assumed that it takes one hour of worker time ($60) to set up and break down the interior wiring in each tent and that each tent would require an annual electrical inspection at a cost of $38. The total annual cost of providing a convenience outlet is estimated at $142 per tent.
c	Assumptions for tent lighting: Each tent will have three 100 watt UL approved fixtures for general lighting and one 75 watt UL listed fixture for task lighting. Using "shop type" lights at a cost of $20 each adds $80 to the compliance. In addition, the state added $5 per lamp per year to cover the cost of setting up and breaking down the lamp, electricity, and light bulbs bringing the lighting cost to $100 per tent. This cost assumes that wire extending from the lamp will be UL approved and will be secured to rigid members of the tent's space frame with plastic fasteners and not enclosed in conduit. Discounting this cost over a seven year period at a 7% interest rate results in yearly costs of $174 and $523 for small and large camps.
d	Assumptions for bed requirement: Operators will rent beds through a program connected with the tent rental program. Option 1: Growers will provide military style cots costing $74 each (aluminum frame, nylon covering). Assuming the cots will be rented twice per year and take one hour of staff time ($10/hr) per tent to set up and breakdown. Assumes no transportation costs (the trucks used to transport tents can accommodate the cots) or storage costs. Discounting the cost of six cots over seven years at 7% discount rate, dividing this cost in half (two rentals/yr.) and adding $10 in setup and breakdown fees results in annual costs of $51 per tent.
	Option 2: Operators use army type bunk beds with mattresses costing $300 per set of two (or $150 per camp occupant) will be required: Beds will be rented twice per year. Discounting this cost of six beds over ten years at 7% discount rate results in annual costs of $64. Additional costs include two additional hours of staff time per tent to set up and breakdown the beds and $20 per year to store six beds. The trucks used to transport tents can accommodate the bunk beds, therefore, no transportation costs. Option 2 cost to operators to rent beds is estimated at $104 per tent.
e	Assumptions for flooring requirements: Option 1: Flooring made of textile or film materials that provides a smooth, flat, stable, walking surface that is weather resistant and prevents the entrance of rodents, snakes, etc. This analysis assumes that growers would meet with requirement with integrated floors supplied with the rented tents. This requirement is estimated to add $24 to the cost of renting each tent.
	Option 2: Floors would comply with State Building Code requirements. This analysis assumes that operators would meet this requirement with a 350 square foot concrete pad costing $1.17/sq. ft. (~$50/yard of concrete plus labor) for a cost of $410. Discounting this cost over a twenty year period at a 7% discount rate adds $38 to the cost of each tent.
f	Assumptions for enhanced cooking facilities: Option 1 requires enclosed cooking areas (current regulations allow food preparation areas to be open on one side). This analysis estimates the cost of adding a fourth concrete wall and a screened opening. Assumes large orchard camp has two food preparation areas each requiring an additional 22 ft. linear of concrete block wall as well as 24 sq. ft. of screened opening. Assuming: Concrete block walls at $10.25/sq. ft. (materials and labor) for an additional cost of $451; $37 for screening material, and $100 in labor cost to install screens. The total cost of the additional requirements for the two food preparation area structures is estimated at $588 or $57 per year when annualized over twenty years at a 7% interest rate.
	For small camps the added requirements affect a single food preparation area adding 22 ft. linear of concrete block wall as well as 24 sq. ft. of screened opening. Assumes: Concrete block walls at $10.25/sq. ft. (materials and labor) for an additional cost of $225; $25 for screening material and $50 in installation labor cost. The total cost of the additional requirements for the two food preparation area structures is estimated at $300 or $28 per year when annualized over twenty years at a 7% interest rate.
	Option 2: Growers would be required to provide in-tent cooking facilities. 1. Operators would have to take several different actions to satisfy this requirement. The necessary equipment includes a four burner stove ($219), sturdy cabinet ($250), sink ($50), faucet ($25), four linear feet of easily cleaned countertop ($30), a five gallon water heater ($125) and a six cu. ft. refrigerator ($269). 2. Requires two hours of plumber time to assemble the various components ($120). Assuming that these fixtures are rented from an entity such as the North Central Community Action Council, they would cost the grower $77 per year per tent. (Fixtures rented twice each year, have $50 per year in storage costs, are depreciated over a 10 year period, and are delivered with the tent-so no transportation costs.)
	3. In-tent cooking facilities would require certain upgrading of infrastructure. Additions to the electrical system include 110-volt outlets dedicated to the refrigerator, the cooking surface, the hot water heater, and the lighting (110 v). Servicing this electrical load would require at least three circuits from each tent to the main panel. (A potential additional cost not included here is upgrading the main electrical panel.) The cost to install the four additional outlets and two additional circuits estimated at $220. Discounting this cost over a seven year period adds $41 to the annual cost of each tent. Overall, the additional cost for enhanced electrical service is $79 per tent. (The cost for an annual electrical inspection is assumed to be included in the cost of a convenience outlet, see footnote b.) An important cost not included in this estimate is that of the additional electricity consumed by the appliances.
	4. New infrastructure will also be needed to supply running water within tents. This analysis assumes that each tent will need an average of 65 feet of water and septic pipes. The cost to dig two 65 ft. trenches (water and septic pipes cannot be co-located in the same trench) is estimated at $85. Discounting this costs over a twenty year period results in annual costs of about $8 per tent. In addition, assumes it takes a plumber two hours ($60/hour) to connect and disconnect the sink system to the running water and septic systems. Overall, infrastructure upgrades add an estimated $128 to the annual cost of each tent.
	Overall, the cost of providing in-tent cooking facilities is estimated at $284 per tent.
g	Assumptions for refrigeration requirement: Current regulations require at least one cu. ft. of refrigeration space per camp occupant. Option 1: Increase required volume to two cu. ft. of refrigeration space per camp occupant, effectively doubling the required volume of refrigeration. 1. A small camp operator would respond to this requirement by adding one 18 cu. ft. refrigerator at a cost of about $400 and 6 cu. ft. refrigerator at a cost of about $269 (assumes camp is currently utilizing two 18 cu. ft. refrigerators). 2. The small camp operator will have to enlarge the size of the central cooking facility at an estimated cost of $733 (24 sq. ft. at $30.5/sq. ft.). (Demolition costs associated with expanding existing facilities not included in this cost estimate.) Overall, this requirement is projected to add $153 to the yearly cost of operating a small camp (enclosure discounted over twenty years, refrigerators over twelve years).
	The large camp operator is predicted to respond to this requirement by adding five, 18 cu. ft. refrigerators at a cost of about $2000. In addition, a large work camp operator will have to enlarge the size of the two central cooking facilities at an estimated cost of $1651 (60 sq. ft. at $27.5/sq. ft.). (Demolition costs associated with expanding existing facilities not included in this cost estimate.) Overall, this requirement is projected to add $408 to the annual cost of operating a large camp (enclosure discounted over twenty years, refrigerators over twelve years).
	Option 2: Also requires 2 cu. ft. of refrigeration space per camp occupant, however, as part of the cooking facilities within each tent. The cost difference between 6 and 12 cu. ft. refrigerator is about $69 ($338 vs. $269). The required tents are large enough to accommodate the larger refrigerator and therefore, operators would not need to rent a larger and more expensive tent. Discounting the cost difference over twelve years at a 7% discount rate results in a per tent annual cost of $8.69 for both large and small camps. Additional electrical consumption is ignored in this analysis.
h	The proposed rule would require growers to test for nitrates prior to opening the camp. The cost of this testing is about $30.
	Other requirements that growers may face for the first time relate to the inspection of temporary worker housing water supply systems (specifically tent camps). These requirements are not new. Current regulations state that growers must "design, construct, maintain, and operate the water system in accordance with chapter 246-290." However, recent Department of Health inspections of temporary work camp drinking water systems revealed that many did not comply with these requirements. To address this situation, the state is planning a higher level of enforcement. Thus, while not new, many growers will face these requirements for the first time. This analysis includes the cost of complying with these requirements as they may affect a grower's willingness to provide a camp. Bringing a well and distribution system into compliance with current regulations would require an existing water system sanitary survey (about $300), a water quality sample ($300), and a review of an existing water system approval workbook ($250). Annualizing this cost over a twenty year period would result in annual costs of approximately $100 per year for both large and small camps. The overall cost of meeting the nitrate and inspection requirements is $110 per year for both large and small camps.
	The estimated cost assumes that no problems are uncovered during the sanitary survey and existing water system approval process. Recent Department of Health inspections of temporary work camp drinking water systems (includes more than just cherry harvest camps) revealed that a significant portion had problems needing to be addressed. As a result, some growers could face costs considerably higher than estimated here.

RCW 34.05.328 applies to this rule adoption. ESSB 5599 (chapter 374, Laws of 1999) requires the Department of Labor and Industries and the Department of Health to adopt joint rules for the licensing, operation, and the inspection of temporary worker and cherry harvest housing and the enforcement of these rules. Though RCW 34.05.328 (5)(b)(iii) and (v) exempts this rule from the significant legislative rule analysis, the Department of Labor and Industries voluntarily applied this analysis.

(6) Must notify the department of a transfer of ownership.

(7) Must cooperate with the department or health officer during on-site inspections.

[]

If a licensed operator meets the requirements provided in this section, then the operator may participate in the self-survey program. This means an operator is allowed to conduct a self-survey for two years. On the third year the department will conduct an on-site verification survey to assure compliance with this chapter and determine if the temporary worker housing still meets the requirements of the self-survey program.

(1) To be in the self-survey program the operator must:

(a) Meet the requirements of WAC 246-358-025;

(b) Not have had any valid complaints;

(c) Have had two consecutive years without any deficiencies or have had only very minor deficiencies (for example one or two screens torn, missing a few small trash cans, etc.); and

(3) When licensed temporary worker housing changes ownership, the new licensed operator must comply with the requirements of subsection (1) of this section before being eligible to be on the self-survey program.

[]

(1) The maximum occupancy for operator-supplied housing will be based on:

(a) The square footage of the housing facility; and

(b) The number of bathing, food handling, handwashing, laundry, and toilet facilities.

(2) The maximum occupancy for worker-supplied housing will be based on:

(a) The number of spaces designated for worker-supplied housing by the operator; and

(b) The number of bathing, food handling, handwashing, laundry, and toilet facilities in excess of those facilities required for operator-supplied housing.

[]

Conditions may exist in operations that a state standard will not have practical use. The director of the department of labor and industries may issue a variance from the requirements of the standard when another means of providing equal protection is provided. The substitute means must provide equal protection in accordance with the requirements of chapter 49.17 RCW and chapter 296-350 WAC, variances.

Applications for variances may be reviewed and investigated by the department of labor and industries and the department of health. Variances granted will be limited to the specific case or cases covered in the application and may be revoked for cause. The variance shall remain prominently posted on the premises while in effect.

Variance application forms may be obtained from the Department of Labor and Industries, P.O. Box 44625, Olympia, Washington 98504-4625 or the Department of Health, P.O. Box 47852, Olympia, Washington 98504-7852, upon request. Requests for variances from safety and health standards shall be made in writing to the director or the assistant director, Department of Labor and Industries, P.O. Box 44625, Olympia, Washington 98504-4625. (Reference RCW 49.17.080 and 49.17.090.)

[]

The operator must:

(1) Locate and operate a site to prevent a health or safety hazard and it is:

(a) Adequately drained and any drainage from and through the housing must not endanger any domestic or public water supply;

(c) At least 200 feet from a swamp, pool, sink hole, or other surface collection of water unless there is a mosquito prevention program for those areas;

(d) Large enough to prevent overcrowding of necessary structures. The principal housing area for sleeping and for food preparation and eating must be at least 500 feet from where livestock are kept; and

(e) The grounds and open areas surrounding the shelters must be maintained in a clean and sanitary condition.

(2) Must develop and implement a temporary worker housing management plan and rules to assure that the housing is operated in a safe and secure manner and is kept within the approved capacity. Additionally, the licensed operator must:

(a) Inform occupants of the rules, in a language the occupant understands by providing individual copies of the rules to each occupant or posting the rules in the housing area;

(b) Restrict the number of occupants in the temporary worker housing to the capacity as determined by the department.

(3) When closing housing permanently or for the season, complete the following:

(a) Dispose of all refuse to prevent nuisance;

(b) Fill all abandoned toilet pits with earth; and

(c) Leave the grounds and buildings in a clean and sanitary condition.

[]

The operator must:

(1) Provide a water system that is:

(a) Approved as a Group A public water system in compliance with chapter 246-290 WAC or provide proof the temporary worker housing receives water from an approved Group A public water system; or

(b) Approved as a Group B water system in compliance with chapter 246-291 WAC.

Note: A "same farm exemption" applies to a public water system serving only one single-family residence and a system with four or fewer connections all of which serve residences on the same farm.

Note: If a system has fifteen or more connections, regardless of the population, it is a Group A water system.

(2) Provide an adequate and convenient hot and cold water supply for drinking, cooking, bathing, and laundry purposes.

Note: An "adequate water supply" means the storage capacity of the potable water system must meet the requirements of ASHRAE 1999 Applications Handbook, chapter 48, Water Systems.

(3) Ensure that the distribution lines are able to maintain the working pressure of the water piping system at not less than fifteen pounds per square inch after allowing for friction and other pressure losses.

(4) When water is not piped to each dwelling unit, provide cold, potable, running water under pressure within one hundred feet of each dwelling unit.

(5) When water sources are not available in each individual dwelling unit, provide one or more drinking fountains for each 100 occupants or fraction thereof. Prohibit the use of common drinking cups or containers from which water is dipped or poured.

(6) When water is unsafe for drinking purposes and accessible to occupants, post a sign by the source reading "Do not drink. Do not use for washing. Do not use for preparing food" printed in English and in the native language of the persons occupying the housing, or marked with easily understood pictures or symbols.

[]

The operator must:

(1) Provide sewage disposal systems in accordance with local health jurisdictions.

(2) Connect all drain, waste, and vent systems from buildings to:

(a) Public sewers, if available; or

(b) Approved on-site sewage disposal systems that are designed, constructed, and maintained as required in chapters 246-272 and 173-240 WAC, and local ordinances.

[]

The operator must ensure that:

(1) Electricity is supplied to all dwelling units, kitchen facilities, shower/bathroom facilities, common areas, and laundry facilities;

(2) All electrical wiring and electrical equipment in a camp must meet the electric standards of applicable building codes;

(3) Each habitable room in a camp has at least one ceiling-type light fixture and at least one separate floor-type or wall-type convenience outlet;

(4) Laundry, toilet rooms, shower/bathrooms, and rooms where people congregate have at least one ceiling-type or wall-type fixture;

(5) General lighting and task lighting is adequate to carry on normal daily activities;

(6) Adequate lighting is provided for safe passage for camp occupants to handwashing sinks and toilets. Note: Lighting requirements may be met by natural or artificial means;

(7) Wiring and fixtures are installed in accordance with department of labor and industries regulations, chapter 19.28 RCW and local ordinances, and maintained in a safe condition.

[]

An operator must:

(1) Construct buildings to provide protection against the elements and comply with the State Building Code, chapter 19.27 RCW, and Temporary worker housing construction standard, chapter 246-359 WAC, applicable state and local ordinances, codes, regulations, and this part. Any shelter meeting these requirements is acceptable.

(2) Identify each dwelling unit and space used for shelter by posting a number at each site.

(3) Maintain buildings in good repair and sanitary condition.
