Studies at Lehigh University have
show that over estimates of emissions, or positive measurements
bias errors can be as high as 20% in some cases. An over
estimate of emission is penalized at the rate of $250,000.00
per 1% of
over estimate of emissions PER YEAR at a normal coal fired power
plant.
History:
In 1990 the Clean Air Act set out a plan based on market driven
reduction of emissions (part 75), as apposed to its more
traditional command and control based system of emissions
control.
By 1994 most electrical utilities had purchased and install
CEMS to comply with the requirements of part 75. There are
over 3000 CEMS now in service meeting part 75 reporting requirements.
Each of these systems is required to perform a Relative Accuracy
Test Audit (RATA) to insure the accuracy of the CEMS, AND determine
the amount of bias of the CEMS system.
The results of this bias test is that under estimates of emissions
are corrected upward with a bias factor and over estimates
of emissions go uncorrected. This creates a situation
in that an over estimate of emission is penalized at the rate
of $250,000.00
per 1% of over estimate of emissions PER YEAR at a normal coal
fired power plant.
Under estimates of emissions are corrected upward, thus, if the RATA test is in error to the up side, or the CEMS
is measuring to the high side an additional over estimate
of emission is artificially created.
At no cost to you!
At no cost to you, Shaw will conduct a site review of the
CEMS to find areas of improvement and trouble spots. This would
also include a pre-RATA review of the site. Shaw will require
for this survey the past years daily drift data, and the past
2 to 3 years of RATA tests. This will determine if there are
credits to be saved, and how much.
Emissions credits savings program.
Based on the results of this study, Shaw will develop a tailored
program for emissions credits savings, projected credit savings,
and payment of the program out of emissions credit savings.
The results of this program may be, changes to CEMS procedures
and /or equipment. Changes to operating procedures are also
considered.
The combination of improved CEMS operation, and Shaw performing
a very accurate RATA test should result in a significant
saving in emissions credits.
Found money.
After entering in to an agreement, Shaw will provide a detailed
program with specific yardstick savings and mile markers. By
sharing in the credit savings, Shaw will be able to provide
services and product to you out of your found money.
You will not only be saving emissions
credits but you will also be saving on the products and services
Shaw will bring
to the table…. A win-win situation.
