Cost Estimation, Potential Regulations

A.1. Training

a. Worker Training (TRAIN-01, 02, 03, 04, 05, 06, 07)

Baseline

Step 1. Calculate Baseline Costs, Farm

• Four categories of trainers eligible to conduct worker safety training with differing costs 

(wage, from BLS (2008)): 

o trainers of handlers and certified applicators ($37.87/hr); 

o individuals who have completed a train the trainer program ($37.87/hr);

o certified applicators ($28.21/hr); and

o handlers ($20.83/hr).

• EPA assumes training typically last 30 minutes, based on the length of training videos.

• The annual frequency that a training session is led by a certain category of trainer is a 

function of the proportion of trainings led by different categories and the total number of 

trainings per year. Based on conversations with state officials, certified applicators 

(frequently the agricultural employer) lead most training sessions while pesticide 

handlers (who lack certification) rarely conduct sessions. EPA assumes trainings are 

distributed among the groups:

o trainers of handlers and certified applicators (14%); 

o individuals who have completed a train the trainer program (10%);

o certified applicators (75%); and

o handlers (1%).

• EPA assumes that the average number of training sessions conducted for each WPS farm 

is a function of farms size, especially the number of workers per farm. Given data on the 

number of farm workers and farms hiring labor (NASS, 2008):

o Large WPS farms (more than $750,000 in revenue/year) with more than 10 

employees hold an average of 4.5 training sessions per year. These farms include 

fruit, nut, and vegetable farms, nurseries, and greenhouses and average about 57 

workers/farm. Many workers will be temporary, hired for peak activities like 

thinning and harvesting and sessions will be conducted throughout the year.

o Large WPS farms with fewer than 10 employees hold an average of 0.9 training 

sessions per year. These farms primarily cultivate field crops such as grains,
Page 2 of 148

oilseed, and cotton with more permanent workers and average about 5 

workers/farm.

o Small WPS farms with more than 10 employees hold an average of 2.2 training 

sessions per year. Again, these farms include fruit, nut, and vegetable farms, 

nurseries, and greenhouses with an average of nearly 15 workers/farm, many of 

whom are temporary workers; sessions will be conducted throughout the year.

o Small WPS farms with fewer than 10 employees hold an average of 0.71 training 

sessions per year (weighted average of 0.725 trainings/year by large-small farms 

and medium-small farms employing an average of 3.2 workers and 0.65 

trainings/year by small-small farms with 2.5 workers/farm). These farms 

primarily cultivate field crops such as grains, oilseed, and cotton or are very small 

fruit, nut, and vegetable farms, nurseries, and greenhouses (those with less than 

$100,000 in revenue/year) with an average of 3.0 workers/farm.

• For simplicity, EPA calculates the weighted average across all WPS farms and obtains 

and average of one training per year. The more detailed baseline is used to compare 

options for annual training (TRAIN-03 and 05) and for evaluating the total incremental 

cost (Appendix B). Table A.1.a-2 presents the simplified estimation of the cost per WPS 

farm.

Step 1. Calculate Baseline Costs, Worker

• Worker wages, including 30% for benefits, are $13.43/hr (BLS, 2008).

• Workers trained each year account for 48.9% of the total workforce.

o Excludes workers employed less than five days, which EPA calculates to be less 

than 1.4% of total workforce, assuming 5% of part-time employees are employed 

less than five days; part-time employees are estimated to be 27.5% of total 

workforce (NASS, 2007 and 2008a).

o Includes 15.8% of total workforce who are new hires employed more than five 

days – based on a 16% new hire rate (DOL, 2005) out of remaining 98.6% of 

workforce.

o Includes 33.1% of total workforce who are returning workers – based on 40% 

retraining rate (20% whose training has expired after 5 years and 20% whose 

training cannot be verified) out of remaining 82.8% of total workforce.

• EPA assumes an abbreviated training takes 3 minutes.

• Workers taking an abbreviated training account for 5.3% of total workforce

o Includes workers employed less than five days (less than 1.4%, as above)

o Includes less than 4.0% of total workforce who are new hires receiving 

abbreviated training prior to full training – based on 25% of new hires employed 

more than five days (15.8% of total workforce, as above).

• Abbreviated training is given individually to each worker by the owner/operator whose 

time is valued at $28.21/hr, including benefits (BLS, 2008).

Step 2. Calculate Per-Actor Costs of Potential Requirement

• Per-farm parameters are as in the baseline (Table A.1.a-2), except for the probability of 

conducting a training.

• EPA assumes that, on average, each WPS farm will conduct 1.5 trainings per year, 

because farms will not be allowed to delay training of new hires until other workers who 

need training can be assembled.

• Trainings are distributed across training groups as in baseline.

• Worker wages are as in the baseline.

• Workers trained each year will account 49.6% of total workforce

o New hires – 16% of workforce (DOL, 2005)

o Returning workers (remaining 84% of workforce) whose training has expired 

after 5 years (around 20%) or whose training cannot be verified (another 20%), 

i.e., 33.6% of workforce.

• In the first year, trainees will account for 50.8% of total workforce

o Includes returning workers who have worked less than five days per year in the 

past and have received only a summary training. EPA calculates that this group 

accounts for 1.2% of total workforce, i.e., 5% of part-time employees, who are 

27.5% of total workforce (NASS, 2007 and 2008a), of whom 16% are new hires.

Step 3. Estimate Regional Level Baseline and Compliance Costs

There are 394,658 WPS farms employing 2,322,610 workers (NASS, 2008 [Census of Ag]). 

WPS farms, defined as those hiring labor, are distributed across regions in the same proportion 

as all farms.

Step 4. Calculate the PV of Costs.

Step 5. Estimate the Regional Incremental Cost of the Potential Requirement.

Calculating the present value (PV) of the baseline and potential cost streams follows the 

methodology presented in Chapter 3.3.1 of the Economic Analysis. In this case, we consider two

factors that change over time. First, under the potential regulation, the per-worker cost declines 

to $3.33 in Years 2 through 10. Second, the number of farms in the U.S. is declining at a rate of 

0.47% per year and the number of farm workers is declining at 2.14% per year.

• EPA assumes that, on average, a WPS farm conducts 1.5 trainings per year because all 

workers need to be trained and some farms will not be able to schedule all workers for 

training at the same time.

o EPA assumes that, on average, a large WPS farm with ten or more workers 

conducts 6.25 training sessions per year, as under TRAIN-03 (a 38.9% increase 

over baseline).

o EPA assumes that, on average, a large WPS farm with fewer than 10 workers 

conducts 1.3 training sessions per year (44.4% increase over baseline).

o EPA assumes that, on average, a small WPS farm with ten or more workers 

conducts 3.1 training sessions per year (40.9% increase over baseline).

o EPA assumes that, on average, a small WPS farm with fewer than 10 workers 

conducts 1.1 training sessions per year (56.1% increase over baseline).

• Trainings are distributed across training groups as in baseline.

• On average, per-farm costs are equivalent to TRAIN-01, Require Full Training prior to 

use of pesticides. See Table A.1.a-4.

There are 22,224 large WPS farms with 10 or more workers and 32,066 large WPS farms with 

fewer than 10 workers; together these large WPS farms employ 1,084,121 workers. There are 

18,116 small WPS farms with 10 or more workers and 322,254 small WPS farms with fewer 

than 10 workers; together small WPS farms employ 1,238,489 workers. WPS farms, defined as 

those hiring labor, are distributed across regions in the same proportion as all farms.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• EPA assumes that, on average, a WPS farm conducts 1.3 trainings per year to account for 

the larger number of workers to be trained.

• Trainings are distributed across training groups as in baseline (Table A.1.a-2).

• See Table A.1.a-8: Potential Cost, per WPS farm, Full Training prior to pesticide use w/ 

Exception/Right-to-Know (TRAIN-02)

• Trainees account for 59.0% of the total workforce.

o Excludes workers employed less than five days, which EPA assumes account for 

under 1.4% of total workforce, i.e., 5% of part-time employees, who are 27.5% of 

total workforce (NASS, 2007 and 2008a);

o Includes new hires, i.e., 16% of remaining workforce or 15.8% of workers

o Includes 55% of the remaining workforce returning from the previous year 

(46.2%), less 25% of returning handlers who are covered by handler training 

(2.9%), or 43.3% of total workforce

• Abbreviated trainings occur as in the baseline

• Provision would require annual training except for farms with fewer than 10 workers, if 

there were no new employees and the same pesticides were used on the farm as in years 

with training.
Page 14 of 148

• EPA assumes that, on average, a WPS farm conducts 1.4 trainings per year, compared to 

1.5 trainings in the annual training without exceptions (TRAIN-03). Trainings are 

distributed across trainer categories as in baseline.

o EPA assumes that, on average, a large WPS farm with ten or more workers 

conducts 6.25 training sessions per year, as under TRAIN-03.

o EPA assumes that, on average, a large WPS farm with fewer than 10 workers 

conducts 1.15 training sessions per year (27.8% increase over baseline), compared 

to 1.3 sessions per year without the exception (44.4% increase over baseline).

o EPA assumes that, on average, a small WPS farm with ten or more workers 

conducts 3.1 training sessions per year, as under TRAIN-03.

o EPA assumes that, on average, a small WPS farm with fewer than 10 workers 

conducts 0.99 training sessions per year (40.7% increase over baseline), compared 

to 1.10 sessions per year without the exception (56.1% increase over baseline).

• There is an overall reduction of 4.9% in the number of workers trained each year 

compared to TRAIN-03.

o Large farms with less than 10 workers hold 11.5% fewer trainings compared to 

TRAIN-03 equivalent to 11.5% fewer workers trained on such farms. This 

implies about 1.8% decrease in workers on all large WPS farms who are trained, 
Page 15 of 148

i.e., 89.8% (from TRAIN-03) times 98.2% of workers or 88.2% of workers on 

large farms will be trained annually.

o Small farms with less than 10 workers hold 9.7% fewer trainings compared to 

TRAIN-03, thus 9.7% fewer workers trained on such farms. This implies about 

7.6% decrease in workers on all small WPS farms who are trained, i.e., 89.8% 

times 92.4% of workers or 82.8% of workers on small farms will be trained 

annually.

Step 1. Baseline

Other State Baselines -- California: same as potential regulation, see Step 2 below.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• EPA assumes that, on average, a WPS farm conducts 1 training per year as in baseline.

• Trainings are distributed across training groups as in baseline.

• EPA assumes training will last 45 minutes.

Step 3. Estimate Regional Level Baseline and Compliance Costs

California currently requires an expanded worker training similar to TRAIN-05. Baseline costs 

are, therefore, the same as in Table A.1.a-16 and 17. There are 394,658 WPS farms employing 

2,322,610 workers (NASS, 2008 [Census of Ag]). WPS farms, defined as those hiring labor, are 

distributed across regions in the same proportion as all farms.

Step 4. Calculate the PV of Costs.

Step 5. Estimate the Regional Incremental Cost of the Potential Requirement.

Calculating the present value (PV) of the baseline and potential cost streams follows the 

methodology presented in Chapter 3.3.1 of the Economic Analysis. In this case, we consider two 

factors that change over time. First, the requirement would be delayed two years to allow for the 

training content to be developed. Thus, baseline costs are used in the first two years and 

potential compliance costs in years three through ten. Second, the number of farms in the U.S. is 

declining at 0.47% per year and the number of farm workers is declining at 2.14% per year.

• See TRAIN-10 (Table A.1.c-1).

• A storage box is needed to store 5 years of records. Cost is $4.23 (Staples, 2008).

• A storage box is expected to last 5 years, so in any given year, about 20% of farms will 

need to purchase a box.

Baseline

Step 1. Calculate Baseline Costs

• Three groups are eligible to conduct worker safety training at differing wage rates, 

including 30% additional cost for benefits (BLS, 2008): 

o trainers of handlers and certified applicators ($37.87/hr); 

o individuals who have completed a train the trainer program ($37.87/hr); and 

o certified applicators ($28.21/hr).

• EPA assumes training typically last 45 minutes.

• EPA estimates that large WPS farms conduct 0.525 handler trainings per year, on 

average.

o Large WPS farms, employing two handlers on average, have a 65.6% chance of 

employing a handler who needs trained, given that 32.8% of handlers will be 

trained each year (see below).
Page 28 of 148

o EPA assumes that there are 4 trainings for every 5 farms that need a handler 

trained, as some farms are able to share resources.

• EPA estimates that large-small WPS farms conduct 0.246 handler trainings per year, on 

average.

o Large-small WPS farms, with one handler on average, have a 32.8% chance of 

employing a handler who needs trained, given that 32.8% of handlers will be 

trained each year (see below).

o EPA assumes that there are 3 trainings for every 4 farms that need a handler 

trained, as some farms are able to share resources and large-small WPS farms are 

more common than large WPS farms.

• CHPEs, employing over six handlers on average, likely have about two handlers to train 

each year. Thus, CHPEs are likely to conduct a handler training every year.

• The annual probability of a training conducted by a given type of trainer is the frequency 

of trainings derived above multiplied by the distribution of training among the types of 

trainer, which EPA assumes is as follows:

o trainers of handlers and certified applicators (14%); 

o individuals who have completed a train the trainer program (10%); and 

o certified applicators (76%).

• WPS and CHPE handler wages, including 30% for benefits, are $20.83/hr and $20.10/hr, 

respectively (BLS, 2008).

• EPA assumes training typically last 45 minutes.

• EPA calculates that 32.8% of handlers will be trained each year, based on the following.

o Includes 16% of handlers, those who are new hires – based on a 16% new hire 

rate for all farm employees(DOL, 2005)

o Includes 16.8% of handlers, who are returning handlers whose training has 

expired after 5 years (20% of remaining 84% of handlers).

• Parameters for WPS farms or CPHEs will be the same as in the baseline except for the 

number of trainings per year per farm or firm.

• EPA estimates that large WPS farms conduct 0.8 handler trainings per year, on average.

o Large WPS farms will have, on average, two handlers to train.

o EPA assumes that, as in the baseline, there are 4 trainings for every 5 farms that 

need a handler trained, as some farms are able to share resources.

• EPA estimates that large-small WPS farms conduct 0.5 handler trainings per year, on 

average.

o Large-small WPS farms will have, on average, one handlers to train.

o EPA assumes that there are 2 trainings for every 4 farms that need a handler 

trained, as some farms are able to share resources and more farms will have 

handlers to train than in the baseline.

• EPA assumes that CPHEs will conduct, on average, 1.3 handler trainings each year, to 

account for the larger number of handlers that must be trained.

• The distribution of trainers will be as in the baseline.

Step 3. Estimate Regional Level Baseline and Compliance Costs

California already requires annual training of handlers; thus, baseline costs are the same as for 

the potential requirement. There are 54,289 large WPS farms and 139,237 large-small WPS 

farms (NASS, 2008 [Census of Ag]). Given EPA assumptions that large farms employ 2 

handlers, on average, and large-small establishments employ 1, there are a total of 247,815 

handlers. WPS farms and handlers are distributed across regions in the same proportion as total 

farms. There are 2,793 CPHEs employing 17,080 handlers, also distributed across regions in the 

same proportion as total farms (Dun & Bradstreet, 2010; NAAA, 2008).

Step 3. Estimate Regional Level Baseline and Compliance Costs

California requires handler training equivalent to the potential requirement; thus baseline costs 

are the same as for the potential requirement. There are 54,289 large WPS farms and 139,237 

large-small WPS farms (NASS, 2008 [Census of Ag]). Given EPA assumptions that large farms 

employ 2 handlers, on average, and large-small establishments employ 1, there are a total of 

247,815 handlers. WPS farms and handlers are distributed across regions in the same proportion 

as total farms. There are 2,793 CPHEs employing 17,080 handlers, also distributed across 

regions in the same proportion as total farms (Dun & Bradstreet, 2010; NAAA, 2008).

Step 4. Calculate the PV of Costs.

Step 5. Estimate the Regional Incremental Cost of the Potential Requirement.

Calculating the present value (PV) of the baseline and potential cost streams follows the 

methodology presented in Chapter 3.3.1 of the Economic Analysis. In this case, we consider two 

factors that change over time. First, the requirement would be delayed two years to allow for the 

development of training material. Thus, baseline costs are used in the first two years and 

potential compliance costs in years three through ten. Second, the number of farms in the U.S. is 

declining at 0.47% per year and the number of farm workers is declining at 2.14% per year.

Step 3. Estimate Regional Level Baseline and Compliance Costs

California requires expanded handler training, equivalent to an additional 15 minutes (see Table 

A.1.c-13 and 14). There are 54,289 large WPS farms and 139,237 large-small WPS farms 

(NASS, 2008 [Census of Ag]). Given EPA assumptions that large farms employ 2 handlers, on 

average, and large-small establishments employ 1, there are a total of 247,815 handlers. WPS

Step 2. Calculate Per-Actor Costs of Potential Requirement

• EPA assumes that the WPS owner/operator spends about 3 minutes collecting and 

recording information, and 1 minute storing information, i.e., 4 minutes or 0.067 hours.

• To keep the records, each operation will require at most one folder costing about $0.20 

(Staples, 2008).
Page 40 of 148

• The annual probability of collecting/storing the information is the frequency at which a 

farm or firm has a handler undertake training. From the baseline (Table A.1.c-2), there is 

a 0.328 probability that an individual handler takes the training

o Large WPS farms, employing two handlers on average, have a 65.6% chance of 

having a handler take a training.

o Large-small WPS farms, employing one handler on average, have a 32.8% chance 

of having a handler take training.

o CPHE will likely have one training with an average of about 2 handlers trained 

each year.

• Each handler marks a separate acknowledgement.

• EPA assumes that it will take a handler about 30 seconds to mark acknowledgement of 

training.

• EPA assumes that the handler trainer spends 45 seconds obtaining the acknowledgements 

from the trainees and, if necessary, sending them to the handler’s employer.

• As in the baseline, 32.8% of all handlers receive training.

• The probability of a category of trainer obtaining an acknowledgement from a given 

handler is the probability of the handler receiving training (32.8%) times the probability 

of the category of trainer administering the training, which, from the baseline, is as 

follows. 

o trainers of handlers and certified applicators (14%); 

o individuals who have completed a train the trainer program (10%); and

There are 54,289 large WPS farms and 139,237 large-small WPS farms (NASS, 2008 [Census of 

Ag]). Given EPA assumptions that large farms employ 2 handlers, on average, and large-small 

establishments employ 1, there are a total of 247,815 handlers. WPS farms and handlers are 

distributed across regions in the same proportion as total farms. There are 2,793 CPHEs 

employing 17,080 handlers, also distributed across regions in the same proportion as total farms 

(Dun & Bradstreet, 2010; NAAA, 2008). Current California requirements exceed the potential 

requirement; thus baseline costs are constrained to equal the cost of the potential requirement.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• As above, except that each operation will also need a storage box costing about $4.23 

(Staples, 2008) for the records.

• The storage box lasts five years, giving an annual probability of 0.2 that a farm or firm 

purchases one.

Step 3. Estimate Regional Level Baseline and Compliance Costs

There are 54,289 large WPS farms and 139,237 large-small WPS farms (NASS, 2008 [Census of 

Ag]). Given EPA assumptions that large farms employ 2 handlers, on average, and large-small 

establishments employ 1, there are a total of 247,815 handlers. WPS farms and handlers are 

distributed across regions in the same proportion as total farms. There are 2,793 CPHEs 

employing 17,080 handlers, also distributed across regions in the same proportion as total farms 

(Dun & Bradstreet, 2010; NAAA, 2008). Current California requirements are equivalent to the 

potential requirement.

f. Training Verification (TRAIN-18, 19, 20)

Baseline

Step 1. Calculate Baseline Costs

• EPA produces and distributes training cards to states at cost; in 2010, EPA spent $23,900 

for 400,000 cards or about $0.06 per card.

• Trainers must fill out and distribute the cards; tests by EPA staff indicate it takes about 2 

minutes per card to enter the name, date of training, and other pertinent information.

• Trainers belong to different categories as explained in Appendix A.1. The probability a 

trainer from a given category provides a trainee the verification card is the probability 

that a worker or handler receives training times the probability that the training is led by a 

trainer in that category.

• EPA calculates that 48.9% of WPS workers and 32.8% of WPS and CPHE handlers 

receive training each year. See Baselines for worker training (A.1.a) and handler training 

(A.1.d).

Baseline, Subtropical, Northeast, and Northwest

Given the number of states requesting EPA-issued verification cards from these regions in 2010, 

EPA treats them as if half the states participate in the program. Thus, the probability of a worker 

or handler in these regions receiving a verification card is half that shown in Table A.1.f-1 and 

baseline costs are also half.

Baseline, Midwest, Ohio Valley, and Texas/Mountain West

Given the small number of states requesting EPA-issued verification cards from these regions in 

2010, EPA treats them as if these states do not participate in the program. The probability of all 

actions is zero and the baseline costs are also zero.

TRAIN-18. Eliminate training verification program.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• All per-employee costs are zero.

Step 3. Estimate Regional Level Baseline and Compliance Costs

There are 2,322,610 WPS workers (NASS, 2008 [Census of Ag]). There are 54,289 large WPS 

farms and 139,237 large-small WPS farms (NASS, 2008 [Census of Ag]). Given EPA 

assumptions that large farms employ 2 handlers, on average, and large-small establishments

A.2. Hazard Communication

a. Application information (HAZCOM-01)

Baseline

Step 1. Calculate Baseline Costs

• EPA assumes the owner/operator of a WPS farm spends 5 minutes per application 

gathering and recording information on the product used, the field treated, the date 

treated and the duration of the REI.

• The operator’s time is valued at $28.21/hr, consisting of the wage and an additional 30% 

for benefits (BLS, 2008).

• EPA assumes a single sheet of paper is sufficient to record the information about each 

application.

• Paper costs $0.09/sheet (Staples, 2008).

• Posting the information is assumed to take one minute.

• EPA calculates that WPS farms make an average of 15.4 pesticide applications per year.
Page 53 of 148

o EPA assumes an average of 20 applications per year, conditional on applying 

pesticides

o About 77.1 percent of WPS farms will make pesticide applications in any given 

year (NASS, 2008).

• The owner/operator of a WPS farm spends the same amount of time gathering and 

recording the information as in the baseline.

• The owner/operator spends about 6 minutes per request providing the information to an 

employee or an employee’s representative.

• The frequency of applications is as in the baseline.

• EPA assumes that there will be a request for information in about 25% of applications.

Step 3. Estimate Regional Level Baseline and Compliance Costs

There are 394,658 WPS farms in the United States (NASS, 2008 [Census of Ag]). WPS farms, 

defined as those hiring labor, are distributed across regions in the same proportion as all farms. 

Current requirements in California and in Texas are equivalent to the potential requirement. 

Thus, baseline costs are equivalent to potential costs for these two regions.

b. Pesticide information (HAZCOM-02, 03, 04)

Baseline, Pesticide-Specific Information

Step 1. Calculate Baseline Costs

• No current requirements for pesticide information, but the agricultural employer will 

nearly always have access to a copy of the pesticide label. Even if the application is 

made by a CPHE, the grower will need a copy to ensure compliance with postapplication label requirements such as the REI.

• The owner/operator of a WPS farm time is valued at $28.21/hour (BLS, 2008)

• The owner/operator spends about 4 minutes obtaining the label either from the pesticide 

distributor or on-line (based on EPA internet searches).

• EPA assumes that pesticide-specific information would be need for half the average 

number of application because the same pesticide is likely to be used on multiple fields. 

Thus, 10 applications weighted by 77.1% of WPS farms making an application in a given 

year.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• The owner/operator of a WPS farm spends an additional 4 minutes obtaining the SDS

either from the pesticide distributor or on-line (based on EPA internet searches).

• Based on a sample of products found on line, labels average 20.8 pages in length and 

SDS average 6.7 pages. Assuming double-sided printing, a copy of the label and SDS

will require 13.7 pages, on average.

• EPA assumes that pesticide-specific information would be need for half the average 

number of application because the same pesticide is likely to be used on multiple fields.

• EPA assumes that half the WPS farms will pay for a copy at the pesticide distributor and 

half will print a copy from the internet.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• The owner/operator of a WPS farm spends about 1 minutes filing information sheets per 

application.

• Application information takes 1 sheet of paper ($0.09). (See Table A.2-a.1)

• The WPS farm will have one folder ($0.20) per season.

• The WPS farm will need one storage box over the five-year retention period.

• EPA calculates that WPS farms make an average of 15.4 pesticide applications per year. 

(See Table A.2-a.1)

• About 77.1 percent of WPS farms will make pesticide applications in any given year 

(NASS, 2008) and will need a folder for records.

• A storage box lasts five years and EPA assumes that every WPS farm will eventually 

have a record.

There are 394,658 WPS farms in the United States (NASS, 2008 [Census of Ag]). WPS farms, 

defined as those hiring labor, are distributed across regions in the same proportion as all farms. 

Current requirements in Texas are equivalent to the potential requirement HAZCOM-05, without 

the storage box. Thus, baseline costs for the region are equivalent to the potential costs shown in

d. Crop Sheet (HAZCOM-07)

Baseline

Step 1. Calculate Baseline Costs

• In the baseline, registrants print a label for each product. Cost is national.

• EPA previously found that the average cost of printing labels to be $4,589.50, based total 

printing costs that average $5,069, including $479.50 to produce a new printing plate 

(EPA, 2005). A new printing plate is not needed under baseline conditions.

• Labels are assumed to be printed about every 3 years for each product.

New Regulation

HAZCOM-07. Print ‘crop sheet’ with label.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• A new printing plate with additional safety information would be needed for the initial 

printing.

• EPA assumes that crop sheets would add about 5% to the cost of a printing plate and to 

the printing costs. Labels currently average about 20 pages while a crop sheet is about 

one page. This may be a substantial underestimate, however, because multiple crop 

sheets would be necessary for a single product that is registered for multiple crops and for 

crops grown under different production practices in different regions of the U.S.

o A new printing plate would cost $503.48.

o Printing costs would increase to $4,818.98.

• Printing of crop sheets would be phased in over about three years in conjunction with 

normal label printing schedule.

Step 5. Estimate the Regional Incremental Cost of the Potential Requirement.

Printing of crop sheets would be phased in over about three years in conjunction with normal 

label printing schedule. After three years, cost per product would fall to the annual cost of 

reproduction, $1,606.33.

Printing of crop sheets is a national-level activity.

A.3. Notification

a. Warning signs during REI (NOTIFY-01, 02, 03)

Baseline, WPS farms excluding greenhouse

Step 1. Calculate Baseline Costs

• Non-greenhouse farms, including nurseries, may either provide oral notification or post 

warnings except for certain products requiring both types of notification; both activities 

are conducted by the owner/operator.

• Warning signs cost $5.66 each (Gemplers)

• EPA assumes WPS farms typically provide oral notification when given the choice, 

which is assumed to take 3 minutes. However, if there are a high number of workers per 

farm, it may be less costly to post the information rather than inform workers orally.

• EPA assumes that 2 signs are usually posted at a time and these signs can be reused. 

WPS farms with worker housing adjacent to a field will need to post a third sign.

o Farms will likely only need 2 or 3 signs due to few simultaneous postings.
Page 65 of 148

• EPA assumes that it takes 10 minutes to post a sign and later take it down, which is done 

by the owner/operator. Posting two signs takes 20 minutes; posting three signs takes 30 

minutes.

• EPA calculates annual average frequencies for oral notification by farm size, based on 20 

applications per year, if pesticides are used. EPA also assumes that 1.1 oral notifications 

will be made, on average, for each application to account for workers in different 

locations.

o Large farms will make 13.9 oral notifications per year, on average (notify workers 

orally for 70% or 14 applications, 1.1 notifications per application, 90.2% chance 

of making an application).

o Large-small farms will make 19.8 oral notifications per year, on average (notify 

workers orally for all applications, 1.1 notifications per application, 89.7% chance 

of making an application).

o Medium and Small-small farms will make 14.3 oral notifications per year, on 

average (notify workers for all applications, 1.1 notifications per application, 

64.9% chance of making a pesticide application).

• EPA calculates annual average frequencies for the purchase of signs by farm size.

o Large farms are assumed to purchase 4 or 6 REI signs, for two simultaneous 

postings, depending on whether worker housing is adjacent to a field.

 Six signs are purchased with annual frequency of 0.122 (90.2% of large 

farms make pesticide applications, 27.1% of large farms are assumed to 

need 6 signs due to adjacent worker housing, and signs are purchased 

every other year, i.e., 0.902 · 0.271 · 0.5)

 Four signs are purchased with an annual frequency of 0.329 (90.2% of 

large farms make pesticide applications, 72.9% of large farms are assumed 

to need 4 signs, signs are purchased every other year, i.e., 0.902 · 0.729 · 

0.5).

o Large-small farms are assumed to purchase 2 or 3 signs since simultaneous 

postings will be rare.

 Three signs are purchased with annual frequency of 0.081 (89.8% of 

large-small farms make pesticide applications, 18.0% of large-small farms 

are assumed to need 3 signs due to adjacent worker housing, signs are 

purchased every other year, i.e., 0.898 · 0.180 · 0.5)

 Two signs are purchased with an annual frequency of 0.368 (89.8% of 

large-small farms make pesticide applications, 82.0% of large-small farms 

are assumed to need 2 signs, signs are purchased every other year, i.e., 

0.898 · 0.820 · 0.5).

o Medium and Small-small farms are assumed to purchase 2 or 3 signs since 

simultaneous postings will be rare.

 Three signs are purchased with annual frequency of 0.071 (64.9% of small 

farms make pesticide applications, 5.5% of small farms are assumed to 

need 3 signs due to adjacent worker housing, signs are purchased every 

other year, i.e., 0.649 · 0.055 · 0.5)

 Two signs are purchased with an annual frequency of 0.307 (64.9% of 

small farms make pesticide applications, 94.5% of small farms are 
Page 66 of 148

assumed to need 2 signs, signs are purchased every other year, i.e., 0.649 · 

0.945 · 0.5).

• EPA similarly calculates annual average frequencies for posting signs by farm size.

o Large farms are assumed to post 2 or 3 REI signs, depending on whether worker 

housing is adjacent to a field.

 Three signs are posted, on average, 1.95 times per year (8 posting events 

out of 20 applications, 90.2% of large farms make pesticide applications, 

27.1% of large farms are assumed to post 3 signs due to adjacent worker 

housing, i.e., 8 · 0.902 · 0.271)

 Two signs are posted, on average, 5.26 times per year (8 posting events 

out of 20 applications, 90.2% of large farms make pesticide applications, 

72.9% of large farms are assumed to post 2 signs, i.e., 8 · 0.902 · 0.729).

o Large-small farms are assumed to post 2 or 3 REI signs, depending on whether 

worker housing is adjacent to a field.

 Three signs are posted, on average, 0.323 times per year (2 posting events 

out of 20 applications, 89.8% of large-small farms make pesticide 

applications, 18.0% of large-small farms are assumed to post 3 signs due

Step 2. Calculate Per-Actor Costs of Potential Requirement

• Parameters are as in the baseline unless otherwise noted.

• EPA assumes that there will be some overlap in posting, implying that non-greenhouse 

WPS farms will need 4 or 6 signs available at a time.

• EPA assumes that 8 pesticides of 20 applications will have REIs greater than 48 hours, 

including the 2 ‘double notification’ applications.
Page 68 of 148

o A large non-greenhouse WPS farm will not be affected by the revision as they 

already post for some applications.

o A large-small non-greenhouse WPS farm will make 13.8 oral notifications. There 

will be 14 occasions for oral notification (including 2 double notifications), each 

occasion averages 1.1 notifications to reach all workers on-site, and 89.8% of 

large-small non-greenhouse WPS farms make pesticide applications (NASS,

Step 2. Calculate Per-Actor Costs of Potential Requirement

• Parameters are as in the baseline unless otherwise noted.

• EPA assumes that there will be some overlap in posting, implying that non-greenhouse 

WPS farms will need 4 or 6 signs available at a time.

• EPA assumes that 6 pesticides of 20 applications will have REIs greater than 72 hours, 

including the 2 ‘double notification’ applications.

o A large non-greenhouse WPS farm will be unaffected by the revision.

o A large-small non-greenhouse WPS farm will make 15.8 oral notifications. There 

will be 16 occasions for oral notification (including 2 double notifications), each 

occasion averages 1.1 notifications to reach all workers on-site, and 89.8% of 

large-small non-greenhouse WPS farms make pesticide applications (NASS, 

2008b).

o Large-small farms are assumed to post 2 or 3 REI signs, depending on whether 

worker housing is adjacent to a field. Two signs are posted, on average, 4.42

times per year (6 posting events out of 20 applications, 89.8% of large-small 

farms make pesticide applications, and 82.0% of large-small farms are assumed to 

post 2 signs, i.e., 6 · 0.898 · 0.820); 3 signs are posted, on average, 0.968 times per 

year (6 posting events out of 20 applications, 89.8% of large-small farms make 

pesticide applications, 18.0% of large-small farms are assumed to post 3 signs due 

to adjacent worker housing, i.e., 6 · 0.898 · 0.180).

o A medium or small-small non-greenhouse WPS farm will make 11.4 oral 

notifications. There will be 16 occasions for oral notification (including 2 double 

notifications), each occasion averages 1.1 notifications to reach all workers onsite, and 64.9% of large-small non-greenhouse WPS farms make pesticide 

applications (NASS, 2008b).

o Medium and Small-small farms are assumed to post 2 or 3 REI signs, depending 

on whether worker housing is adjacent to a field. Two signs are posted, on 
Page 72 of 148

average, 3.68 times per year (6 posting events out of 20 applications, 64.9% of 

small farms make pesticide applications, and 94.5% of large-small farms are 

assumed to post 2 signs, i.e., 8 · 0.649 · 0.945); 3 signs are posted, on average, 

0.213 times per year (6 posting events out of 20 applications, 64.9% of small 

farms make pesticide applications, 5.5% of small farms are assumed to post 3 

signs due to adjacent worker housing, i.e., 8 · 0.649 · 0.055).

o Workers on large farms receive 10.6 notifications, as in the baseline.

o Workers on large-small farms receive 11.7 notifications; large-small farms make 

16 oral notifications out of 20 applications, there is an 80% chance a worker will 

be on-farm during the REI, and 91.1% of workers are employed on large-small 

WPS farms making a pesticide application (NASS, 2008b) (16 · 0.8 · 0.911).

o Workers on medium and small-small farms receive 9.0 notifications per year. 

Small farms make 16 oral notifications out of 20 applications, there is an 80%

Step 3. Estimate Regional Level Baseline and Compliance Costs

There are 393,779 non-greenhouse WPS farms including 54,115 large, 138,951 large-small, and 

200,713 medium- and small-small enterprises. These WPS farms and nurseries employ 

2,297,773 workers, of which 1,063,629 are employed on large farms, 647,896 are employed on 

large-small farms, and 586,248 are employed on medium- and small farms (NASS, 2008 [Census 

of Ag]). WPS farms, defined as those hiring labor, are distributed across regions in the same 

proportion as all farms.

Baseline, WPS greenhouses (indoor production)

Step 1. Calculate Baseline Costs

• Greenhouse operations are required to post warnings for all applications.

• Oral notification is provided for double notification products.
Page 75 of 148

• Warning signs cost $5.66 each (Gemplers)

• EPA assumes oral notification takes 3 minutes.

• EPA assumes that 2 signs are usually posted at a time and these signs can be reused. 

Farms will likely need 4 signs due to simultaneous postings.

• EPA assumes that it takes 10 minutes to post a sign, which is done by the owner/operator. 

Posting two signs takes 20 minutes.

• EPA calculates there will be, on average, 1.64 oral notifications per large greenhouse per 

year and 1.21 oral notifications per year per small greenhouse. EPA assumes 2 

applications out of 20 require oral notification and 1.1 oral notifications will be made, on 

average, for each application to account for workers in different locations; 74.7% of large 

greenhouses and 55.2% of small greenhouses make pesticide applications in a year 

(NASS, 2008).

• EPA calculates an annual average frequency of 0.374 and 0.276 for the purchase of signs

by large and small greenhouses, respectively. Signs last for two seasons and 74.7% of 

large greenhouses and 55.2% of small greenhouses make pesticide applications in a year 

(NASS, 2008).

• EPA similarly calculates that large greenhouses will post signs, on average, 14.9 times 

per year (20 applications and 74.7% of large greenhouses make pesticide applications)

and that small greenhouses will post signs 11.0 times per year (20 applications and 55.2% 

of large greenhouses make pesticide applications).

• Workers in large greenhouses receive 1.26 oral notifications, on average, per year and 

workers in small greenhouses receive 0.83 oral notifications per year. There are 2 

notification events, 80% of workers are on-site to receive notification, and 78.5% of large 

greenhouse workers and 51.6% of small greenhouse workers are employed on 

greenhouses making pesticide applications (NASS, 2008).

Step 2. Calculate Per-Actor Costs of Potential Requirement

• Parameters are as in the baseline unless otherwise noted.

• Large greenhouses will find it cheaper to post REIs than to notify the large number of 

empoyees.

• EPA calculates there will be, on average, 3.64 oral notifications per small greenhouse per 

year. As in the baseline, EPA assumes 2 applications out of 20 require oral notification 

(double notification products) and another 4 oral notifications will be made for products 

with a REI less than 4 hours; 1.1 oral notifications will be made, on average, for each 

application to account for workers in different locations; and 55.2% of small greenhouses 

make pesticide applications in a year (NASS, 2008) [6 · 1.1 · .552].

• EPA calculates that small greenhouses will post signs, on average, 8.8 times per year (16 

applications and 55.2% of small greenhouses make pesticide applications).

• Workers receive 1.65 oral notifications, on average, per year. There are 6 double 

notification events, 80% of workers are on-site to receive notification, and 55.2% of 

greenhouse workers are employed on greenhouses making pesticide applications (NASS, 

2008) [6 · 0.8 · 0.552].

Baseline

Step 1. Calculate Baseline Costs

• There are no baseline requirements

New Regulation

NOTIFY-04. Keep record of oral notifications for 2 years.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• The employer must prepare a written copy of the warning, which takes one sheet of 

paper. The employer obtains the acknowledgement of the employees on the warning 

sheet and stores the acknowledgement, which requires a folder.

• EPA assumes that preparing the warning takes 2 minutes, obtaining workers’ 

acknowledgement takes 6 minutes, and storing the acknowledgement takes one minute.

• The annual frequency depends on farm size and type.

o A large WPS farm (excluding greenhouses) is expected to have 12.6 oral 

notification events per year, on average. EPA assumes a large WPS will have 14 

oral notifications out of 20 applications (see A.3.a) and that 90.2% of large WPS 

non-greenhouse farms make pesticide application each year (NASS, 2008). 

Because workers may not be together or on site at the same time, EPA assumes 

that there will be 13.9 occasions to obtain acknowledgements, i.e., 10% more 

times than applications (Table A.3.a-1).

o A small WPS farm (excluding greenhouses) is expected to have 15.0 oral 

notification events per year, on average. EPA assumes a large WPS will have 20 

oral notifications, i.e., all 20 applications (see A.3.a) and that 75.1% of small 

WPS non-greenhouse farms make pesticide application each year (NASS, 2008). 

Because workers may not be together or on site at the same time, EPA assumes 

that there will be 16.5 occasions to obtain acknowledgements, i.e., 10% more 

times than applications.

o A WPS greenhouse is expected to have 1.18 oral notification events per year, on 

average. EPA assumes a WPS greenhouse will have 2 oral notifications out of 20 

applications (see A.3.a) and that 59.0% of WPS greenhouses make pesticide 

application each year (NASS, 2008). Because workers may not be together or on 

site at the same time, EPA assumes that there will be 1.30 occasions to obtain 

acknowledgements, i.e., 10% more times than applications.

• Folders are needed with the same frequency as a farm of given size or type makes 

pesticide applications.
Page 79 of 148

• Workers spend 30 seconds acknowledging receipt of information.

• Workers on large and small WPS farms and nurseries acknowledge receipt of information 

10.6 times and 13.0 times, on average, each year. EPA assumes 16 oral notifications out 

of 20 applications, there is an 80% chance a worker will be on-farm during the REI, and 

94.6% of workers employed on large WPS farms and nurseries and 81.4% of workers 

employed on small WPS farms and nurseries are employed on establishments making a 

pesticide application (NASS, 2008b) (16 · 0.8 · 0.946 and 16 · 0.8 · 0.814).

• Workers in greenhouses acknowledge receipt of information 1.18 times per year, on 

average. There are 2 notification events, 80% of workers are on-site to receive 

notification, and 73.8% of greenhouse workers are employed in greenhouses making 

pesticide applications (NASS, 2008).

There are 393,779 non-greenhouse WPS farms (54,115 large and 339,664 small) employing 

2,297,476 workers (1,063,664 on large establishments and 1,234,144 on small establishments)

and 879 WPS greenhouses employing 24,837 workers (NASS, 2008). WPS farms, defined as 

those hiring labor, are distributed across regions in the same proportion as all farms.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• A writable sign costs $7.15 (Gempler).

• EPA assumes the owner/operator of the establishment will spend 3 minutes updating each 

sign with application information prior to posting, i.e., 6 minutes for updating 2 posters 

and 9 minutes for updating 3 posters.

• Annual frequency of posting is as in the baseline. See Tables A.3.a-1 and A.3.a-13.

New Regulation

NOTIFY-08. REI warning signs if worker housing within 100 feet of treated area.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• Revision specifies distance, but is unlikely to result in changes. Parameters are as in the 

baseline.

Step 3. Estimate Regional Level Baseline and Compliance Costs

There are 393,779 non-greenhouse WPS farms and 879 WPS greenhouses (NASS, 2008). Since 

the revision provides clarity only, baseline and potential costs are the same (see baseline in Table 

A.3.d-3).

Step 4. Calculate the PV of Costs.

Step 5. Estimate the Regional Incremental Cost of the Potential Requirement.

The number of farms in the U.S. is declining at 0.47% per year. Data do not distinguish between 

greenhouses and other types of farms. Since the revision provides clarity only, PV of baseline 

and potential cost are the same (see baseline in Table A.3.d-4). Incremental costs are zero.

Step 6. Estimate National Level Incremental Cost of the Potential Requirement.

This revision is for clarity. Incremental costs are zero.

New Regulation

NOTIFY-09. REI warning signs placed every 100 feet around perimeter of field.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• As a representative case for non-greenhouse WPS farms, EPA takes a square, 40-acre 

field. Each side is 1,320 feet in length, necessitating 13 or 14 signs per side or about 53

signs around the perimeter.

o Smaller fields would require fewer signs, but less regularly shaped fields could 

require more. For example, if the field above is cut in half across opposite 

corners to form a triangular field of 20 acres, two sides would be 1,320 feet and 

the third would be 1,867 feet. The longer side would need 19 signs for a total of 

45 to 47 signs.

• As a representative case for WPS greenhouses, EPA takes a rectangular 1-acre plot 66 

feet by 660 feet, requiring 7 signs on the longer sides or 14 signs total. To account for 

simultaneous posting, a greenhouse is assumed to need 28 signs.

• At 10 minutes per sign, it would take a WPS farm nearly 9 hours to post and later remove

53 signs around a field and it would take a WPS greenhouse 2 hours 20 minutes to 

post/remove 14 signs.

• Annual frequency for the purchase of signs is as in the baseline, with no distinction for 

fields near worker housing.

• Annual frequency for posting events is as in the baseline, with no distinction for fields 

near worker housing.

e. Early Entry Notification Requirements (NOTIFY-10 and 11)

Baseline

Step 1. Calculate Baseline Costs

• The operator’s time is valued at $28.21/hr, consisting of the wage and an additional 30% 

for benefits (BLS, 2008).

• EPA assumes that gathering the currently required information takes 1 minute.

• EPA assumes that providing the information takes 3 minutes.

• EPA calculates the probability of an early entry event to be 30.8%

o EPA assumes that there will be an early entry event about 1 every 50 applications

or 2% of applications.

o Assuming 20 applications farm per year, there is a 40% probability a WPS farm 

applying pesticides will have an early entry event.

o 77.1% of WPS farms apply pesticides in any given year (NASS, 2008), there is a 

33.4% chance a WPS farm will have an early entry event.

• Workers spend 3 minutes receiving information from the owner/operator.

• EPA calculates that there is a probability of 17.5% that any individual worker will be 

involved in an early entry event.

o As above, there is a 40% probability a WPS farm applying pesticides will have an

early entry event.

o EPA assumes that, on average, 50% of the establishment’s workers will be 

involved in a particular early entry event

o 87.4% of workers are employed on WPS farms that apply pesticides in any given 

year (NASS, 2008).

Step 1. Calculate Baseline Costs

There are currently no federal or state requirements.

New Regulation

NOTIFY-12. Records of information provided prior to early entry to be kept for 2 years.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• One record sheet is sufficient for all workers involved to indicate receipt of information.

• Farm owner/operator is responsible for receiving and storing records.

• EPA assumes it will take 3 minutes to collect the acknowledgments from workers.
Page 97 of 148

• EPA assumes it will take 4 minutes to sort and file the information and 

acknowledgements.

• To keep the records, each operation will require a folder costing about $0.20 (Staples,

2008).

• There is a 30.8% probability that a WPS farm will have an early entry event and an 

17.5% probability that a worker will be part of an early entry event in any given year.

Baseline

Step 1. Calculate Baseline Costs

• A safety poster costs $6.08 (Gempler).
Page 100 of 148

• WPS establishments post 1 safety poster at a central location if an application is made.

o The probability that a large WPS farm makes an application is 0.902 (NASS, 

2008b).

o The probability that a small WPS farm makes an application is 0.750 (NASS, 

2008b).

• EPA assumes it takes 2 minutes to set up the safety poster.

• A sign lasts about 3 years, so one-third of WPS farms will need to purchase a sign in a 

year that the farm posts.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• Owner/operator spends about 3 minutes adding additional information to display.

• Information, such as emergency contacts, is unlikely to change frequently, so updating 

occurs with each new poster, implying the same annual probability as a purchase.

The number of farms in the U.S. is declining at 0.47% per year. This requirement would be 

phased in over two years to allow for WPS farms to purchase appropriate signs. Thus, the PV 

for the potential requirement is calculated using baseline costs for the first two years of the 10-

year time horizon.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• Parameters are as in the baseline unless otherwise indicated.

• Decontamination posters cost $7.95 (Gempler).

• EPA assumes that large WPS establishments will have 2 locations for decontamination 

displays.

• EPA assumes all small WPS establishments will have 1 or 2 locations for 

decontamination displays.

• Annual frequency for large farms is as in NOTIFY-14 (Table A.3.g-2).

• EPA calculates that 21.0% of small WPS farms will purchase two displays each year.

o Posters last 3 years, implying a 33.3% replacement rate.

o 63% of small WPS farms are large and medium small WPS farms that apply 

pesticides in a given year (NASS, 2008b), which is also the probability of posting 

two displays.

• EPA calculates that 4.0% of small WPS farms will purchase posters each year.

o Posters last 3 years, implying a 33.3 replacement rate.

o 12% of small WPS farms are small-small WPS farms that apply pesticides in a

h. Notification of farm by CPHE (NOTIFY-18)

Baseline

Step 1. Calculate Baseline Costs

• Commercial applicators must notify a farm, nursery, or greenhouse prior to an application 

and inform the operation when there are any changes in the schedule or the product used. 

EPA guidance has indicated that notification must be made so that agricultural employers 

can inform their employees of any areas under a REI.
Page 109 of 148

New Regulation

NOTIFY-18. Codify guidance on communication between CPHE and agricultural 

employer.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• EPA anticipates no changes from codification of existing guidance.

A.4. Age

a. Minimum age for workers in early entry activities (AGE-01 and 02)

Baseline

Step 1. Calculate Baseline Costs

• EPA assumes that 14-15 year old WPS workers are paid $6.71/hour, 50% of adult 

worker.

• EPA assumes that 16-17 year old WPS workers are paid $8.06/hour, 60% of adult 

workers.

• EPA assumes that early entry tasks take no more than 8 hours.

• EPA calculates the likelihood of a youth worker to participate in early entry activities to 

be 0.001 for 14-15 year olds and 0.007 for 16-17 year olds.

o EPA assumes that 14-15 year old workers make up 0.82% of the workforce and 

16-17 year old workers make up 3.74% of the workforce, which is twice the 

proportion of handlers reported by the National Agricultural Worker Survey 

(DOL, 2005).

o EPA assumes there is a 40% chance that a WPS farm will have an early entry 

event each year (see A.2.d).

o EPA assumes that half the workforce will participate in an early entry event.

o 87.4% of workers are employed on a WPS farm that makes a pesticide application 

in a given year (NASS, 2008b).

Step 3. Estimate Regional Level Baseline and Compliance Costs

There are 2,322,610 farm workers in the United States (NASS, 2008 [Census of Ag]). Florida 

statutes prohibit workers under the age of 18 from working around pesticides unless proper field 

entry allowances are observed. EPA assumes this applies to early entry activities in agriculture

and sets baseline costs for the Subtropical region to the cost of the potential revision.

b. Minimum age for handlers (AGE-03 and 04)

Baseline

Step 1. Calculate Baseline Costs

• EPA assumes that 14-15 year old WPS handlers are paid $10.41/hour, 50% of adult 

handlers.

• EPA assumes that 16-17 year old WPS handlers are paid $12.50/hour, 60% of adult 

handlers.

• WPS handlers under the age of 18 spend, on average, 50 hours per year in handling 

activities (DOL, 2005).

• According to surveys of agricultural workers, 0.47% of pesticide handlers are under 16 

and 1.87% are between 16 and 18 years old (DOL, 2005). These percentages are 

weighted by 89.9%, the proportion of handlers employed on WPS farms making pesticide 

applications in a given year.

• EPA assumes that, of the 16 and 17 year old WPS handlers, 40% are 16 and 60% are 17, 

implying 0.75% of handlers are 16 and 1.12% are 17.

• EPA assumes CPHE handlers under the age of 18 spend 640 hours per year in handling 

activities: 40 hr/wk for 16 weeks.

• EPA assumes that 1% of CHPE handlers are 16 and 17 years old, with 0.4% age 16 and 

0.6% age 17.

Step 3. Estimate Regional Level Baseline and Compliance Costs

There are 54,289 large WPS farms and 139,237 large-small WPS farms (NASS, 2008 [Census of 

Ag]). Given EPA assumptions that large farms employ 2 handlers, on average, and large-small 

establishments employ 1, there are a total of 247,815 handlers. WPS farms and handlers are 

distributed across regions in the same proportion as total farms. There are 2,793 CPHEs 

employing 17,080 handlers, also distributed across regions in the same proportion as total farms 

(Dun & Bradstreet, 2010; NAAA, 2008).

establishments employ 1, there are a total of 247,815 handlers. WPS farms and handlers are 

distributed across regions in the same proportion as total farms. There are 2,793 CPHEs 

employing 17,080 handlers, also distributed across regions in the same proportion as total farms 

(Dun & Bradstreet, 2010; NAAA, 2008).

Step 1. Calculate Baseline Costs

• None

• Workers may be sent into a treated field during the REI to conduct certain critical tasks.

• EPA assumes that double notification products comprise about 10 percent of applications.

• Early entry events are assumed to occur about 1 out of 50 applications and EPA assumes 

50% of workers would be involved with activities in the treated field (see A.2.d, 

NOTIFY-07 and 08). Given 20 applications per year of which 2 are double notification 

products, there is a 4% probability a WPS farm applying pesticides will have an early 

entry event associated with a double notification product. Since 87.4% of WPS farms 

apply pesticides in any given year (NASS, 2008), there is a 1.7% chance a WPS 

farmworker will be involved in an early entry event involving a double notification 

product.
Page 118 of 148

New Regulation

ENTRY-03. Limit entry into restricted area treated with double notification products to 4 

hours.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• No measurable impacts. Most tasks (e.g., equipment repair, arranging frost protection) 

would not take more than 4 hours to accomplish. There may be some extra management 

effort to rotate workers if tasks go longer.

ENTRY-04. Limit entry into restricted area treated with double notification products to 8 

hours.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• No measurable impacts. Rarely would tasks take more than 8 hours to accomplish.

ENTRY-05. Eliminate early entry exemptions.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• This provision would affect WPS farms and family farms as the latter can use the 

exemptions in the WPS.

• EPA assumes there could be a 5% yield loss due to an unmitigated emergency, which 

implies a $13,024 loss in average farm revenue.

o Producers of vegetables, fruits, nursery, and greenhouse crops are most at risk of 

loss due to weather emergencies such as frost or to irrigation problems. WPS

farms in these categories total 193,759 (NASS, 2008b).

o The value of production of these WPS farms was $50.469 billion in 2007 (NASS, 

2008b).

o Average revenue per farm is calculated to be $260,474.

• EPA assumes that 25% of a farm’s acreage could be affected by an unmitigated 

emergency.

• EPA calculates that there is a 9.8% likelihood that a WPS farm will be affected by an 

agricultural emergency and will be a producer of vegetable, fruit, nursery, or greenhouse 

crops.

o There is an early entry event in 1 out of 50 applications, implying a 20% chance 

for a farm making an average of 20 applications.

o 24.6% of all farms using pesticides, including family farms, produce vegetable, 

fruit, nursery, or greenhouse crops (NASS, 2008b).

Step 1. Calculate Baseline Costs

• None. There is no federal requirement.
Page 120 of 148

Baseline, Northwest

Step 1. Calculate Baseline Costs

• Washington state requires monitoring of handlers who work with cholinesterase 

inhibitors (ChIs), especially those working with ChIs more than 30 hours in 30 days. 

• The cost per handler of the testing program is $55.14, given expenditures of $111,595 in 

2007 for 2,024 handlers (Furman, 2007), including handlers that decline testing.

• EPA assumes that each handler spends 30 minutes to get the baseline blood test or to 

officially decline participation and 1 hour travel time, round trip, to the testing center.

• EPA calculates that handlers requiring follow up tests because they work with ChIs at 

least 30 hours in 30 days will spend 2.07 hours, including travel time.

o As for the baseline test, the handler spends 30 minutes for the test and 1 hour 

travel, round trip.

o Handlers obtain an average of 1.4 follow-up tests (Furman, 2007).

• There were 2,024 handlers in the program in 2007, which is 14.1% of all WPS handlers 

in the Northwest region. CPHE handlers do not appear to be included in the program.

• Given that 19.1% of handlers tested in the baseline or declining tests receive follow-up 

tests because they work with ChIs more than 30 hours in 30 days, EPA calculates that 

2.7% of WPS handlers would get follow-up tests.

Baseline, California

Step 1. Calculate Baseline Costs

• EPA assumes that the California testing cost per handler is the same as that in 

Washington although California does not require baseline tests and only tests if handlers 

work with ChIs more than 30 hours in 30 days.

• Time for tests is as calculated for Washington.

• EPA calculates that 9.7% of WPS and CPHE handlers trigger the testing requirement.

o 386 handlers involved in the program in Washington had follow-up tests, i.e., 

worked with ChIs at least 30 hours in 30 days, representing 9.7% of the estimated 

3,971 WPS handlers in the state working on farms that apply pesticides.

o EPA calculates the number of WPS handlers in Washington assuming large farms 

hire two handlers and large-small farms hire one handler. There are 39,284 farms 

in Washington (NASS, 2008) of which, assuming the national distribution holds 

in Washington, 967 are large farms (sales of $750,000 or more) and 2,481 are 

large-small (sales between $100,000 and $750,000). This implies 4,415 WPS 

handlers, of which 89.9% are employed on WPS farms that make a pesticide 

application in a given year (NASS, 2008).

Step 2. Calculate Per-Actor Costs of Potential Requirement

• Parameters are similar to Washington except for annual probability of testing.

• EPA estimates that 45.8% of WPS handlers and 51.0% of CPHE handlers would be 

involved in a national program.

o 2,024 handlers participate in the Washington program, including those who 

decline to be tested, or 45.8% of the estimated 4,415 WPS handlers in the state.

o The probability of a CPHE handler’s involvement in the program is adjusted 

(divided by) to account for the fact that only 89.9% of WPS handlers are 

employed on farms that make a pesticide application (NASS, 2008).

• Follow -up testing is needed for 19.1% of participating handlers (Furman, 2007) or 8.7% 

of WPS handlers and 9.7% of CPHE handlers, as in the California baseline.

employing 17,080 handlers, also distributed across regions in the same proportion as total farms 

(Dun & Bradstreet, 2010; NAAA, 2008) and 89,529 self-employed handlers (commercial 

applicators certified in plant protection) for a total of 106,609 CPHE handlers that would be part 

of a monitoring program.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• In order to limit the time handling ChI pesticides to less than 30 hours in 30 days, the 

handler would have to record the time spent in any ChI application. EPA assumes this 

would take 2 minutes.

• The handler employer would have to track the dates and time to keep a cumulative total 

over the past 30 days, which EPA assumes would take 3 minutes.

• EPA calculates that, on average, a WPS handler will make 1.83 ChI pesticide 

applications per year.

o EPA assumes that 20% of pesticide applications are of ChI pesticides, or on 

average, 4 applications per year per farm.

o EPA calculates that 45.8% of WPS handlers work with ChI pesticides. See 

ENTRY-04 above.

• EPA calculates that, on average, a CPHE handler will make 13.8 ChI pesticide 

applications per year.

o EPA assumes that 30% of pesticide applications are of ChI pesticides, or on 

average, 27 applications per CHPE handler per year.

o EPA calculates that 51.0% of CPHE handlers work with ChI pesticides. See 

ENTRY-04 above.

Step 3. Estimate Regional Level Baseline and Compliance Costs

There are 54,289 large WPS farms and 139,237 large-small WPS farms (NASS, 2008 [Census of 

Ag]). Given EPA assumptions that large farms employ 2 handlers, on average, and large-small 

establishments employ 1, there are a total of 247,815 handlers. WPS farms and handlers are 

distributed across regions in the same proportion as total farms. There are 2,793 CPHEs 

employing 17,080 handlers, also distributed across regions in the same proportion as total farms 

(Dun & Bradstreet, 2010; NAAA, 2008) and 89,529 self-employed handlers (commercial 

applicators certified in plant protection) for a total of 106,609 CPHE handlers that would be part 

of a program. For WPS handlers, Washington and California are assumed to be following a 

similar tracking scheme under the existing ChI monitoring programs. For CPHE handlers, we 

use the California baseline calculated in ENTRY-06.

a. Respirators (PPE-01)

Baseline

Step 1. Calculate Baseline Costs

• WPS Employers and handlers spend about 6 minutes checking the fit of a respirator

together.

• WPS Employers and handlers also spend about 6 minutes providing and receiving 

instruction on the use of a respirator.

• Probability of 34.7% that a WPS handler currently has a respirator check.

o Assumes that, on average, only half of WPS farms applying pesticides will use a 

pesticide that requires a respirator.

o One handler per WPS farm, on average, would be responsible for applying a 

pesticide that requires a respirator.

• EPA estimates that 0.4% of WPS handlers currently obtain an OSHA-type respirator fit 

test because they handle fumigants. EPA’s estimate is based on proprietary market 

survey data on the projected number of farms reporting fumigant applications, averaged 

over 2006 to 2010, multiplied by the proportion of farms that use pesticides that also hire 

labor.

o Data are reported for farmer-applied fumigants in field crops.

o Data are reported on type of fumigant applied for tree, fruit, and vegetable crops.

 EPA assumes all chemigations are farmer-applied.

 EPA assumes that all applications of 1,3-D (including chloropicrin mixes), 

metam sodium, and metam potassium are farmer applied while all 

applications of chloropicrin and chloropicrin mixed with methyl bromide 

and methyl iodide are applied by commercial applicators.

o 33.8% of farms primarily producing field crops that use pesticides also hire labor; 

47.5% of farms primarily producing specialty crops that use pesticides also hire 

labor (NASS, 2008b)1

.

• Fit testing requires that the handler complete an initial medical survey, taking about 30 

minutes to complete (DOL, 2004)

• The survey is evaluated by a registered nurse or a licensed health care provider whose 

time is valued at $42.91 per hour (BLS, 2008).

• 23% of those taking the medical screen will need a follow-up examination (DOL, 2004), 

or about 0.2% of all WPS handlers.

• The follow-up exam takes 2 hours, including travel time.

• Cost for the exam is $101, based on the average cost of an office visit to a general 

practitioner (Machlin and Carper, 2007).

• The fit test takes about 1.5 hours, including travel time, and the material costs about $1 

(DOL, 2004).

• WPS Employers and handlers subsequently spend about 6 minutes providing and 

receiving instruction on the use of a respirator.

 1 This may underestimate the number of WPS farms using fumigants since fumigant use may be more likely on 

farms hiring labor.

• Parameters for CPHE handlers are similar to WPS handlers, except for wages and the 

probability of an action.

• All CPHE handlers are likely to need to use a respirator at some point. CHPEs are 

already subject to OSHA regulations as they are classified as general industry rather than 

specifically as agriculture. Thus, all CPHE handlers will be fit tested in accordance with 

the proposed requirement.

• Self-employed handlers do not provide or receive instruction on respirator use.

• 23% of those taking the medical screen will need a follow-up examination (DOL, 2004), 

or about 1.3% of all CPHE handlers.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• Parameters are identical to baseline respirator fit tests except for frequency/probability of 

action.

• EPA assumes that, on average, each large WPS farm and each large-small WPS primarily 

engaged in crop production (i.e., not farms primarily engaged in livestock production) 

will have one handler obtain a fit test, implying 59.5% of handlers will be fit tested, 

including a medical screen. They will do this as a matter of course so that the handler is 

prepared if a pesticide requiring a respirator must be applied later in the season.

• 23% of those taking the medical screen will need a follow-up examination (DOL, 2004), 

or about 13.7% of all WPS handlers.

• Instruction on use occurs only if pesticide is applied.

• CPHE handler costs are as in the baseline (Table A.6.a-2).

(Dun & Bradstreet, 2010; NAAA, 2008). The requirement also applies to about 69,656 selfemployed commercial applicators working in about 38,311 businesses. California has imposed 

an OSHA-type requirement, thus baseline costs are the same as for the potential requirement.

b. Employees working under Certified Crop Advisors (PPE-02 and 03)

Baseline/Current Practice

Step 1. Calculate Baseline Costs

• Certified Crop Advisors (CCAs) can elect to enter fields during a REI for scouting 

purposes without PPE and those supervised by CCAs can similarly choose to forgo PPE. 

The farm or firm must have decontamination supplies and PPE available, however.

• An employee of a crop advisory working under the supervision of a CCA is assumed to 

be paid $20.10 per hour, the same wage as a CPHE handler.

• A worker/employee under the supervision of a CCA would generally carry a water bottle 

for rinsing eyes. A bottle costs $1.23 (Gemplers).
Page 131 of 148

• A worker/employee would also generally put on PPE (e.g., boots, gloves, etc.) before 

entering the field. EPA assumes this might take 10 minutes.

• EPA assumes that there is a 9.0% chance that a WPS fieldworker might be directed to 

enter a field during a REI under the supervision of a CCA, a 10% occurrence weighted by 

a 90.2 % chance that a large WPS farm makes a pesticide application (NASS, 2008). A 

water bottle would have to be available.

• EPA assumes that there is a 5% chance that the supervising CCA would suggest that the 

worker could forego wearing PPE. In the baseline, therefore, the worker puts on the PPE 

with a probability of 0.086 (90.2% chance of an application x 10% chance of entering the 

field x 95% chance of wearing PPE).

• Similarly, EPA assumes that a non-certified employee of a crop advisory firm will have a 

90% chance of being directed into a field during a REI under the supervision of a CCA. 

A water bottle would have to be available.

• EPA assumes there is a 1% chance that the supervising CCA would suggest the employee

could forego wearing PPE. In the baseline, therefore, the employee puts on the PPE with 

a probability of 0.891 (90% chance of entering the field x 99% chance of wearing PPE).

(NASS, 2008 [Census of Ag]) and EPA assumes there will be one employee working under the

CCA per large WPS farm, on average.

c. Closed Systems (PPE-04)

Baseline

Step 1. Calculate Baseline Costs

• EPA assumes that large and large-small WPS farms and large family farms may own a 

closed system for mixing and loading pesticides that allows an exemption to the use of 

PPEs. Smaller farms would not typically own such a system.

• Filters, costing $17.97/pair (Gemplers), are used in PPE and in closed systems.

• If a farm relies on PPE, it will, on average need 5 filters per year2

.

• If a farm uses a closed system, one filter will last for a year.

• A maintenance kit costs $86.50 (Cherlor Mfg. Co Inc., 2008).

• EPA assumes that 25% of large and large-small WPS farms will not have a closed 

system, but will use PPE. However, 89.9% of large and large-small WPS farms make a 

pesticide application in a given year (NASS, 2008b), thus the probability of needing the 

filters is 0.225.

• The remaining 75% of large and large-small WPS farms have a closed system, of which 

89.9%, or 67.4% of the total, will make a pesticide application and require a filter.

• EPA assumes a 20% probability of a breakdown, thus 13.5% of all large and large-small 

WPS farms that a user will need a maintenance kit (20% of 67.4%).

 2 This assumption is likely high. Given the probability of maintenance, a closed system would cost about $35/year 

or less than the cost of two filters. However, as farms relying on PPE are not affected by the rule, the assumption 

does not affect the estimate of the incremental cost.
Page 135 of 148

• EPA assumes that 50% of large family farms have a closed system; 70.2% percent of 

large family farms use pesticides, thus the probability of using filters is 0.351.

• Given a 20% probability of a breakdown, there is a 7.0% chance that a large family farm 

will need a maintenance kit.

• EPA assumes that CPHEs employing handlers have, on average, two closed systems, 

each requiring a filter every year; self-employed commercial handlers have one system.

• Given a 20% probability of a breakdown, there is a 40% probability that a CPHE will 

need to purchase a maintenance kit and a 20% probability that a self-employed 

commercial handler will need to purchase a kit.

New Regulation

PPE-04. Revise standards for closed systems that allow PPE exemptions; keep record of 

maintenance.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• A closed system that meets the new standards costs $484.92 (Cherlor Mfg. Co Inc., 

2008).

• EPA assumes that one-third of existing closed systems would meet the revised standards, 

one-third of would be replaced by a system that meets the new standards, and one third 

would not be replaced with those farms relying on PPE.

• In case of breakdown, the establishment would need to keep a record of maintenance.

• The owner operator would spend about 1 minute to file the record of maintenance (sheet 

of paper at $0.09) in a folder ($0.20).

Baseline

Step 1. Calculate Baseline Costs

• Employers are required to provide “enough” water for workers. Guidance indicates that 

1 gal is considered sufficient.

New Regulations

SUPPLY-01. Define “enough” water as 1 gal per worker.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• Revision is definitional in nature and no impacts are anticipated.

b. Water for decontamination at early entry events, Field Workers (SUPPLY02)

Baseline

Step 1. Calculate Baseline Costs

• Employers are required to provide “sufficient” water for workers entering a field during 

the REI. Guidance indicates that 1 gal is considered sufficient.

• 1 gal of water costs $0.003/gal, based on the average cost of irrigation water in Kentucky 

(the state with the highest cost) of $1,112/acre-foot (USDA, 2010).
Page 141 of 148

• EPA assumes an early entry event occurs about 1 in 50 applications, implying there is a 

40% probability a WPS farm applying pesticides will have an early entry event (see 

A.2.d.) EPA assumes that, on average, 50% of the establishment’s workers will be 

involved in an early entry event, implying 20% of the workers on WPS farm applying 

pesticides. Since 87.4% of workers are employed on WPS farms that apply pesticides in 

any given year (NASS, 2008), there is an 17.5% chance a WPS worker being involved in 

an early entry event.

c. Water for handler decontamination (SUPPLY-03 and 04)

Baseline

Step 1. Calculate Baseline Costs

• Employers are required to provide “enough” water for handlers. Guidance indicates that 

3 gal is considered sufficient.

• No requirements for facilities.

New Regulations

SUPPLY-03. Define “enough” water as 3 gal per handler.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• Revision is definitional in nature and no impacts are anticipated.

New Regulation

SUPPLY-04. Require showers for handler decontamination.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• Shower construction is estimated to cost $105,000 (Gaylord Entertainment Company, 

2007).

• All WPS farms employing handlers and CPHEs would have to construct shower 

facilities.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• California requires showers at WPS farms and CPHEs that handle organophosphate and 

carbamate pesticides, i.e., cholinesterase inhibitors (ChIs).

• EPA calculates that 9.7% of large and large-small California WPS farms given the 

estimated percentage of handlers involved in the California ChI monitoring program. See 

A.5.d, Baseline, California. A larger percentage of CPHEs is likely to have showers and 

we calculate that 14.6% of California CPHEs have showers (50% higher than the farm 

percentage) given the assumption that 20% of farm applications are with ChIs and 30% 

of CPHE applications are with ChIs.

Step 3. Estimate Regional Level Baseline and Compliance Costs

There are 193,526 large and large-small WPS farms (NASS, 2008 [Census of Ag]) who are 

assumed to employ at least one handler. There are 2,793 CPHEs (Dun & Bradstreet, 2010; 

NAAA, 2008) and EPA estimates another 20,897 self-employed CPHEs may be affected.

Step 5. Estimate the Regional Incremental Cost of the Potential Requirement.

The number of farms in the U.S. is declining at 0.47% per year. The number of CPHEs is 

growing at a rate of 4.27% per year. Construction of showers is a one-time event. No 

maintenance costs are included for Years 2 through 10, thus underestimating the cost of this 

potential requirement.

Baseline

Step 1. Calculate Baseline Costs

• EPA assumes WPS and CPHE handlers will have a pint bottle for water to rinse his/her 

eyes if a pesticide application is made; 89.9% of large and large-small WPS farms, which 

are assumed to employ handlers, make an application in a given year (NASS, 2008).

Step 2. Calculate Per-Actor Costs of Potential Requirement

• Mixing/loading sites, given their purpose, will have water source available.

No additional cost to establishment.

SUPPLY-06. Require portable eyewash station.

Step 2. Calculate Per-Actor Costs of Potential Requirement

• A portable eyewash station costs $279.90, on average (Tuthill, 2008; Gempler’s, 2008).

Step 3. Estimate Regional Level Baseline and Compliance Costs

There are 193,526 large and large-small WPS farms (NASS, 2008 [Census of Ag]). Given EPA 

assumptions that large farms employ 2 handlers, on average, and large-small establishments 

employ 1, there are a total of 247,815 handlers. WPS farms and handlers are distributed across 

regions in the same proportion as total farms. There are 2,793 CPHEs employing 17,080 

handlers (Dun & Bradstreet, 2010; NAAA, 2008) and EPA estimates another 38,311 selfemployed CPHEs, for whom we only consider the additional cost of the eyewash station.

Step 5. Estimate the Regional Incremental Cost of the Potential Requirement.

The number of farms in the U.S. , and therefore the number of handlers employed on farms, is 

declining at 0.47% per year. The number of CPHEs is growing at a rate of 4.27% per year and 

the number of handlers employed by CPHEs is growing at 0.17% per year. Purchase of eyewash 

stations is a one-time event. Maintenance costs of 10% of the purchase price are included for 

Years 2 through 10.
