"Air pollution control officer (APCO)" means the air pollution control officer of the San Joaquin Valley unified pollution control district (district) or his designee.
"Average vehicle readership (AVR)" is the number of employees who arrive at a worksite divided by the number of vehicles those employees use to arrive at the worksite, averaged over the survey week. AVR can be averaged across multiple worksites.
"Buspool" means a privately operated or chartered bus which provides commute transportation on a subscription basis to sixteen (16) or more passengers.
"Carpool" means a vehicle occupied by two to six people traveling together between their residence and their worksite or destination for the majority of the total trip distance. Employees who work for different employers, as well as non-employed people, are included within this definition as long as they are in the vehicle for the majority of the total trip distance.
"Commute trip" means the trip made by an employee from home to the worksite. The commute trip may include stops between home and the worksite.
"Compressed work week" means a regular full-time work schedule which eliminates at least one round-trip commute trip (both home-to-work and work-to-home) at least once every two weeks. Examples include, but are not limited to working three twelve-hour days (3/36) or four ten-hour days (4/40) within a one-week period; or eight nine-hour days and one eight-hour day (9/80) within a two-week period.

(Ord. 491 § 7, 1994)
10.12.090 - Compliance schedule.¶
A. Employer Registration Schedule. Employers who become subject to this chapter shall register with the APCO by September 1, 1994 or within one hundred eighty (180) days after hiring the one hundredth employee.
B. Employee Survey Schedule. Employee surveys shall be conducted within two weeks prior to or two weeks following the employer's survey date as stipulated by the APCO.
Employee transportation survey results are to be submitted to the APCO within forty-five (45) days of the survey week.
Subject to APCO approval, an employee transportation survey conducted prior to the effective dates of the ordinance codified in this section may be submitted to fulfill the requirements of this subsection provided that the survey was conducted within one hundred eighty (180) days of its submittal date and it provides sufficient data to calculate AVR pursuant to subsection A of this section.
Employers who become subject to this rule subsequent to the schedule above due to an increase in employees or the establishment of a new or expanded worksite shall conduct an employee transportation survey within one hundred eighty (180) days after meeting the requirements of Section 10.12.070(B).
(Ord. 491 § 8, 1994)
10.12.100 - Calculations.¶
AVR Calculation. AVR for each affected worksite is to be computed as follows:
A. The employer conducts an employee transportation survey during a survey week.
B. The employer shall calculate the AVR only for those employees who start work or are assigned to the worksite during the peak period.
C. If less than sixty (60) percent of the survey forms are returned for processing from those employees who start work during the peak period, all survey forms not returned shall be counted as single-occupant vehicles for purposes of calculating AVR.
D. If sixty (60) percent or more of the survey forms are returned for processing from those employees who start work during the peak period, one-half of those survey forms not returned shall be assumed to have the same AVR as that calculated from the response to the surveys returned, and one-half shall be counted as single-occupant vehicles for purposes of calculating AVR.
E. The employer shall calculate the AVR for the worksite by dividing the total employee-days for the survey week by the total vehicle trip-days for the survey week.
- AVR = Total Employee Days/Total Vehicle Trip Days. Employee-days shall be determined by the total number of employees who start work or are assigned to a worksite during the peak period each work day Monday though Friday of the survey week. Each day of the survey week that an employee starts work during the peak period counts as one employee-day. For example, an employee who starts work each day Monday through Friday of the survey week between six a.m. and ten a.m. counts as five employees-days. The following procedures are used in totaling employee-days:
Employees telecommuting or are off due to a compressed work week schedule are counted as reporting to the worksite in calculating the total employee-days.
- The following employees are not included in the employee-days total:
a. Employees not working because of vacation, sickness or other time off;
b. Employees who report to a different worksite or an off-site work related activity;
c. Disabled employees.
F. Vehicle Trip Days. Vehicle trip days shall be determined as follows:
The total number of vehicles used by employees who start work or are assigned to the worksite each work day Monday through Friday of the survey week. A vehicle trip-day is based on the means of transportation used for the greatest distance of an employee's home to work commute trip. For example an employee who starts work during the peak period and arrives at the worksite each day of the survey week Monday through Friday in a single occupant vehicle counts as five vehicle trip-days. The following numerical values are used in calculating the total vehicle trip-days:
Single occupant vehicle (drive alone) equals one;
Carpool equals one divided by the number of people in the carpool;
Vanpool equals one divided by the number of employees in the vanpool;
Motorcycle, moped, motorized scooter or motor bike equal one;
Dedicated compressed natural gas vehicle equals one-fourth;
Dedicated propane vehicle equals one-half;
Dual or flexible fueled vehicle equals three-fourths;
The following all equal zero vehicle trip-days:
a. Public transit vehicles,
b. Private buspool or club bus,
c. Vehicle under human power,
d. Pedestrians,
e. Electric vehicle.
G. Random Sample Method. The method described in this section shall be followed when an employer chooses to use a random sample to meet the requirements of this Section.
Employers with four hundred (400) or more employees at a single worksite have the option of calculating AVR based upon a random sample of the employee population. The random sample option is available only for worksites where four hundred (400) or more employees start work during the peak period (six a.m. through ten a.m.).
The size of the random sample depends upon the number of employees who start work during the peak period at the worksite. The means to determine the minimum size of the random sample is described in subsection G(5)(b) of this section.
The sample shall be selected as described in subsection G(5) of this section. Once the sample group has been selected, the employer shall not send additional survey forms to employees beyond the original sample group. Such additional surveys invalidate the result of the survey and void the employ-er's option to utilize the random sample method.
A high response rate is critical to ensure that the random sample produces an accurate AVR for the worksite. The employer should make a concerted effort to obtain a completed survey form from each employee in the sample. All nonrespondents in the sample will be treated as drive alone commuters (i.e. commuting in a single occupant vehicle) for purposes of calculating the worksite AVR.
Basic Random Sample Selection Methodology.
a. The employer shall compile a complete list of employees at the worksite, in alphabetical order and assign a consecutive number to each employee. The employer shall exclude from the list employees who are known to regularly start work outside the six a.m. through ten a.m. peak period.
b. The employer shall determine the number of employees to be included in the random sample using the following formula, where (n) is the sample size and (N) is the number of employees who start work between six a.m. and ten a.m.
n = N/1+O.0026*(N-1)
A sample of size "n" based on this formula should produce an AVR with a sampling error of at most plus or minus 0.05, with ninety-five (95) percent probability. The sample size based on this formula is displayed in the table below:
| Number of Peak Period Employees at worksite | Sample Size |
|---|---|
| 400 to 420 | 200 |
| 421 to 440 | 205 |
| 441 to 460 | 210 |
| 461 to 480 | 214 |
| 481 to 500 | 218 |
| 501 to 550 | 225 |
| 551 to 600 | 235 |
| 601 to 650 | 240 |
| 651 to 700 | 248 |
| 701 to 750 | 255 |
| 751 to 800 | 260 |
| 801 to 850 | 265 |
| 851 to 900 | 270 |
| 901 to 950 | 274 |
| 951 to 1000 | 278 |
| 1001 to 1500 | 300 |
| 1501 to 2000 | 320 |
| 2001 to 3000 | 340 |
| 3001 to 4000 | 350 |
| 4001 to 6000 | 360 |
| 6001 to 10,000 | 370 |
| >10,000 | 380 |
c. In no case can the random sample size be less than indicated in the above table. The employer may choose to include a larger number of employees in the survey. A larger sample group should more accurately represent the entire employee population provided that the employer obtains a high response rate.
d. After the sample size has been determined, the employer shall use a random number list generated by the district to select the sample.
(Ord. 491 § 9, 1994)
10.12.110 - Fees.¶
The fee schedule for Rule 9001 is contained in Rule 3130 (trip reduction plan review fee).
(Ord. 491 § 10, 1994)
10.12.120 - Alternative emission control.¶
At the option of the employer, with approval of the APCO an alternative vehicle emission reduction program may be used which achieves emission reductions equal to or greater than those that would have been achieved if the performance objectives of Rule 9001 were met, and that these alternative measures are not required by any other federal, state or local control measure or regulatory requirement. Such an alternative emission reduction program shall include an update and progress monitoring report to be submitted at least every year.
(Ord. 491 § 11, 1994)
10.12.130 - Delegation requirements.¶
A local jurisdiction may be delegated responsibility for the implementation of this rule by the APCO providing that the local trip reduction ordinance and program to implement the ordinance meet the requirements of the California Health and Safety Code Section 40717(e).
