SCAQMD RECLAIM NOx/SOx





RECLAIM – REgional CLean Air Incentives Market
Started January 1, 1994
Businesses that beat their reduction targets can trade their
credits on the open market. Using market forces allows
pollution to be cut in the most economical way.
Move away from traditional command-and-control rules

Continuous Monitoring of emissions
Perform Daily Calibration
Perform other QA Activities, i.e. RATA
Identify problems for alarming
Display emissions for control, if required
Insure valid emissions data is being collected
Apply appropriate Missing Data Procedures

RECLAIM Valid Hourly Data



Copyright 2009.
All Rights Reserved.
Four (4) Valid 15-Minute Period
Only four (4) Maintenance/QA Hour are valid were the
hour has between 2-3 valid 15-minute periods
Maintenance/QA Hour with 2-3 valid 15-minute periods
beyond the first four hours are invalid
RKI Engineering LLC
RECLAIM Valid 15-Minute Average


Copyright 2009.
All Rights Reserved.
Only one valid minute data is required to calculate a valid
15-minute period
All valid CEMS data are used in the 15-Minute Average
regardless of operations
RKI Engineering LLC
RECLAIM Valid Minute Data (Part 1)

CEMS data is invalid during:





Emissions between 10-95% of range




Calibration in Progress
Maintenance and Quality Assure Activities
CEMS Out of Control
Stack Flow based on Fuel Flow, O2 > 19%
Invalid when emissions is greater than 95% range
Emissions limited to 10% of range when emission drops below
10%
Spike Test can be used to certify analyzer below 10% range

Emission Rate Calculations





NOx Lbs/Hr = 0.1195*NOx (ppmvd)*Stack Flow (mscfh)
SOx Lbs/Hr = 0.1662*SO2 (ppmvd)*Stack Flow (mscfh)
NOx and SO2 are directly measured
Stack Flow can be measured directly or calculated
Calculated Stack Flow

Can be used with consistent fuel type, i.e. Natural Gas
Based on fuel flow, Higher Heating Value (HHV), Fd, O2
For natural gas, HHV default is 1050 and Fd is 8710

Relative Accuracy Test Audit



Determine accuracy of CEMS, Relative Accuracy
Determine Bias Adjustment Factors, 1 or greater
Semi-Annual/Annual RATA


Failed RATA




Invalid CEMS data
RECLAIM Missing Data Procedure is applied
Successful RATA is required to start collecting valid CEMS data
RATA not completed within the required quarter

Meet Incentive – Annual RATA
Request for Variance
RECLAIM Missing Data Procedure still applies
Successful RATA is required to start collecting valid CEMS data

Bias Adjustment Factors (BAF)

NOx/SOx BAF



Stack Flow BAF


NOx Bias Adjust = NOx ppmv * BAF for NOx
SOx Bias Adjust = SOx ppmv * BAF for SOx
Stack Flow Bias Adjust = Stack Flow * BAF for Stack Flow
NOx/SOx Lbs/Hr BAF (Two Methods)

Based on RATA Results


Based on NOx/SOx BAF and Stack Flow BAF

NOx Lbs/Hr Bias Adjust = NOx Lbs/Hr * BAF for NOx Lbs/Hr
NOx Lbs/Hr Bias Adjust = NOx Bias Adjust * Stack Flow Bias
