Q.1 RESOLUTION FOR ENHANCING SIP CREDITABILITY OF INCENTIVE REDUCTIONS

The resolution is available on the District website ( www.valleyair.org ).

Q.2 SAMPLE EMISSION REDUCTION CALCULATIONS USED IN PROTOCOLS

The SJVAPCD Emission Reduction Incentive Program uses California Air Resources Board (ARB) guidance to develop calculations of emission reductions and cost effectiveness of various projects. ARB guidance can be found at http://www.arb.ca.gov/planning/tsaq/mvrfp/mvrfp.htm and http://www.arb.ca.gov/msprog/moyer/moyer.htm . Below are some examples to illustrate the types of calculations that could be found in a protocol applied to a specific project. These are examples only and may not reflect current District practice for calculating incentive-based emissions reductions.

Signal Coordination 

## EXAMPLE

Traffic Signal Coordination The City's master traffic signal controller was replaced with a new controller with expanded capacity.
This allowed 25 more intersections to be

c oordinated.

Inputs to Calculate Cost- Effectiveness: Funding Dollars (Funding):
$ 200,000 Effectiveness Period (Life): 5

y ears Days of use/year (D): 250 Length of congested roadway segment (L): 7.50 miles Traffic Volume during congested period (Congested Traffic): 38,400

ROG Factor 0.32 grams per mile 0.27 grams per mile

PM10 Factor 0.03 “ 0.03 “

Annual Emission Reductions (ROG, NOx, and PM10) in lbs. per year = [(.50)*(VMT)*(Before Speed Factor - After Speed Factor)]/454

g rams per lb.

ROG: [(0.50 * 72,000,000) *(0.32 – 0.27)]/454 = 3,965 lbs. per

y ear NOx: [(.50 * 72,000,000) *(1.20 – 1.16)]/454 = 3,172 lbs. per

y ear PM10: [(.50 * 72,000,000) * (0.03 – 0.03)]/454 = 0 lbs. per year

Capital Recovery Factor (CRF) = (1 + i) n (i) = .22 where n = project life (5 years) (From Table 8) (1 + i) n - 1 and i = discount rate (3%)

Cost-Effectiveness of Funding Dollars = (CRF * Funding)/(ROG + NOx + PM10 ) = [.22 * 200,000] / 7,137 = $6.16 per lb.

FOR CMAQ PROJECTS ONLY: Once emissions reductions have been calculated, add them together (9,515 + 3,172 + 793) and

convert emissions reductions to
k g/day: lbs. reduced per year = 7,137 = 9 kg/day

## EXAMPLE

Class 2 Bikeway Facility

The new Class 2 bike lanes are a critical link in the city bike system, allowing residents bicycle access to education, employment, shopping, and transit. Within one-quarter mile of the project, there is a college, a shopping center, a light rail station, and an office building. The project includes installation of new pavement, signage, and Class 2 bike lane striping along both sides of 1.13 miles of arterials. This is primarily a college town, with a population of 128,000.

A videophone-interviewing project is implemented by the County Probation Department. Videophone equipment is installed for $40,000 at the branch probation offices and two detention centers. Videophone interviewing of 5,000 inmates per year saves 200 one-way trips per week to and from detention centers (a distance of 29 miles on average).

County Trip Reduction Program A county conducts a comprehensive employee trip reduction program, which includes vanpool and carpool programs, telecommuting, compressed work schedules, and guaranteed emergency transportation.Inputs to Calculate CostEffectiveness: Funding Dollars (Funding): $140,000 Effectiveness Period (Life): 1 year One-Way Auto Trips Eliminated Per Week (T) Using Optional Method 1:
