BACKGROUND 

"Clean Screening" is a means of improving motorist convenience and potentially reducing costs associate'"' 

with periodic compliance with an inspection and maintenance (1/M) program. As an alternative to traditional vehii 

emissions inspection and maintenance for all eligible vehicles, Clean Screening in this case utilizing "remotv 

sensing" technology, identifies those vehicles that would not benefit from participation in a traditional emissions 

inspection program i.e., they are clean and would have passed. Measures such as clean screening improve the 

l/M programs' cost effectiveness. 

DISCUSSION 

When remote sensing technology was introduced, the application of the technology was directed at the 

identification of dirty/failing vehicles and not clean vehicles. Various entities to include the Division have conducted 

separate studies all of which concluded that remote emissions sensing results for dirty vehicles were too variable 

and often falsely failed clean vehicles. It has been determined that remote sensing technology can be a reliable 

tool in the identification of clean vehicles. Revisions to Regulation 11 implement the provisions of S.S. '98-182. 

Implementation of a formal, operational clean screen program as proposed would be the first program of its kind 

in the nation. 

Revisions to the original proposal make provision for non-program area motorists, having vehicles 

registered in Larimer County and Weld County, to comply with periodic inspection requirements utilizing Clean 

Screen procedures. Also, the emissions limits for carbon monoxide (CO) has been revised from 1 % to 0.8%, 

further focusing on the cleaner cars . 

Additionally, ·revisions to the regulation codify the provisions of S.B.'98-046 which further clarifies ti 

responsibility of compliance with emissions inspection requirements for vehicles in the process of being sold , 

especially as it may pertain to vehicles that are inoperable or otherwise untestable as defined in rules adopted by 

the Department of Revenue. The program is in place at this time. Regulation 11 would be consistent with 

statutory provisions. 

CONCLUSION 

Clean Screening procedures improve the cost effectiveness of traditional vehicle emissions inspection and 

maintenance programs such as Colorado's AIR Program. Motorists participating in this program who operate 

clean vehicles are rewarded for their efforts and are exempt from inspection for an inspection cycle. 

The statutory directives of S.B.'98-182 and S.B.'98-046 would be satisfied. 

RECOMMENDATION 

The Division requests the Commission to adopt the revisions to Regulation 11 as proposed February 18, 

1999.

ECONOMIC IMPACT ANALYSIS 

for 

AQCC REGULATION N0.11: 

Inspection and Maintenance 

per 

C.R.S. 25-7-110.5 (4)(1) 

Cost Effectiveness Economic Impact Analysis 

2/1/99 

The purpose of this APCD proposal is to incorporate, into Regulation No. 11, the actions taken 

by the 1998 State Legislature to 1) to establish a Clean Screen Program for the Front Range as 

directed in Senate Bill 98-182; and 2) to establish procedures for written notice regarding vehicle 

emissions certification as directed in Senate Bill 98-046. This proposal merely codifies AQCC 

Regulation No.11 with Senate Bill 98-046 legislative directives, as such, changes pursuant to 

98-046 will not be analyzed. Under Senate Bill 98-182 (Clean Screen Program) significant 

policy making authority is granted to the AQCC, as such, a formal EIA will be performed for this 

bill. 

IDENTIFICATION OF THE CUMULATIVE COSTS OF ANY PROPOSED 

CONTROLS/REGULATIONS WITH WHICH AFFECTED BUSINESSES ARE TO 

COMPLY & IDENTIFICATION OF THE DIRECT COSTS TO BE INCURRED BY 

AFFECTED MEMBERS OF THE GENERAL PUBLIC TO COMPLY WITH 

PROVISIONS OF THIS PROPOSAL: 

Per Clean Screen Program directives, the APCD is to establish in Weld and Larimer Counties 

(and potentially El Paso County) a bid process for the purposes of entering into a contract(s) to 

provide, to the citizens of these counties, instrumentation, collection and reporting data for the 

purposes of establishing a Clean Screen Program. Such a program is designed to detect, by 

remote sensing, cars that are within emissions standards (clean screened) and thus will not have to 

be tested at an basic emissions program I&M facJity. The AQCC is also directed to establish, 

through the rulemaking process, the technical nature of the program, which includes 

enforcement, quality assurance, number of vehicles tested, emissions test cut points, etc. 

1 
As envisioned, this program will eliminate certain vehicles from needing a basic emissions test, 

currently performed for a fee of $15.00. Instead of having an emissions test performed for 

$15.00, the motorist will be clean screened and pay a contractor up to $15.00 for the service. 

Because contractor prices are not yet set, it is possible that the motorists may experience a cost 

savings associated with the clean screen program, if the contractor is able to perform the clean 

screen service under the statutory cap of $15.00. As the contractor will be absorbing part of the 

basic emissions certification market in these counties, the testing facilities will experience reduced 

revenues (a multiplication of the $15.00 testing fee). As per current predictions, it is assumed 

that 35% of the cars tested in Weld and Larimer Counties will pass the clean screen and be 

removed from the necessity to be facility tested. In absolute numbers, this translates to an 

estimated 12,000 vehicles in Weld County and 35,000 vehicles in Larimer County. Thus the 

overall decreased testing facility revenues will approximate $180,000 for Weld and $525,000 for 

Larimer County basic emissions testing facilities. The provisions of SB 182 do, however, extend 

the inspection program into the future. 

It is further estimated that a decrease in the demand for testing will decrease the demand for 

persons licensed to provide emissions tests in Weld and Larimer Counties. This decreased 

mechanics demand reduces both jobs for and costs to the testing facilities as well as reduces 

licensing revenues to the State AIR Account. If mechanics demand decreases, the State will not 

collect the $10/mechanic annual renewal fee for each mechanic job lost. 

No estimate for aggregate losses can be estimated at this time because the relationship between 

current worker productivity and the 35% decreased periodic emissions tests is unknown. 

In addition, the reductions addressed in this paragraph are targeted for Weld County and Larimer 

Counties, if El Paso County opts in to the program, additional impacts will be realized. These 

estimates are preliminary. 

AIR POLLUTION REDUCTIONS CAUSED BY THE PROPOSAL and COST PER 

UNIT OF AIR POLLUTION REDUCTIONS CAUSED: 

This proposal will result in an aggregate decrease of 4% excess carbon monoxide and 7% excess 

hydrocarbon emissions of the overall I&M benefits, based on the assumption that 35% of I&Meligible vehicles are exempted form a .periodic emissions inspection. 

COST FOR THE DIVISION TO IMPLEMENT THE PROVISIONS OF THE 

PROPOSAL: 

Costs to the APCD were appraised in the legislative process. Costs borne by the APCD are 

assumed, at this point, to be absorbable within existing program resources.

-FACTSHEET-

"CLEAN SCREEN PROGRAM" 

Clean Screening is an alternative inspection and maintenance (I/M) test. 

,.. Clean Screening is a cost effective means to identify clean vehicles, potentially reducing 

motorist costs. 

Vehicles identified as "clean'', would be exempt from one inspection cycle. 

As proposed, Clean Screening procedures will utilize Remote Sensing Technology. 

As specified by statute, Clean Screening will be introduced in the Larimer County and 

Weld County AIR Program areas. 

Other areas may participate upon request by their Lead Air Quality Planning Agency. 

Individual motorist participation is voluntary. 

Implementing a remote emissions sensing Clean Screen Program does not preclude 

research/investigation into other forms of emissions profiling especially as it would 

pertain to confirmatory procedures for remote sensing.
