Re: Cement Industry Total Hydrocarbon Data 

Dear Keith, 

Attached please find the total hydrocarbon data collected by PCA, as of June 3, 2010. As 

you know, the industry initiated this data collection effort last fall. We had hoped to have the 

testing program completed by April or May, but the current state of the industry, the poor 

economy, and associated cement plant temporary shutdowns, did not make that possible. 

Nevertheless, the data is a significant volume of new information. PCA plans to supplement this 

data shortly with some additional analyses of potential subcategories. 

We do offer a note of caution as you begin your review of the new data. With respect to 

a potential THC standard for new sources, we believe that the Agency should rely strictly on data 

from preheater/precalciner kilns when setting such a standard, as these will be the new kilns of 

the future. Using data for area sources, long wet or long dry kilns for this purpose, we believe 

would be inappropriate. In addition, we continue to believe that the total hydrocarbon emissions 

are driven largely by the concentration of organic compounds in raw materials, primarily the 

limestone, which is completely out of the control of existing plants or those existing plants that 

may be upgraded with new kilns, as neither will be in a position to utilize a new limestone 

source. We, therefore, stand by the recommendations we made in our comments regarding the 

limitations of regenerative thermal oxidizers and minimum emission limits necessary to account 

for the influence of limestone on total hydrocarbon emissions. 

We will share additional thoughts and observations with you on Monday, June 21, and 

discuss in greater detail the additional PCA data analyses. 

Thank you for patience and support associated with PCA’s efforts to collect this 

additional total hydrocarbon data. You may reach me at (202) 408-9494 (or 

aohare@cement.org) to address any questions. 

Sincerely,

DOCUMENTATION OF PCA STUDY THC DATABASES 

Three related databases have been prepared presenting the data collected by the PCA in the 

context of the total hydrocarbon (THC) Subcategorization Study and are documented briefly 

below. 

THC CEMS Data Collected in Study

All of the continuous emissions monitor (CEMS) data collected during the study are contained in 

the Excel spreadsheet: THC Study CEMS Database 2010.06.11.xls. The full CEMS record for 

each kiln is compiled in a separate tab that provides: 

• Individual hourly emissions as reported by the kiln operators 

• A tabular summary and graphical presentation of the hourly data 

• The calculation of daily-average emissions from the hourly values. Because not every 

hour is reported on every day, a decision was made during the study to define a 

“complete” calendar day as one for which at least 18 hours were reported. 

• A tabular summary and graphical presentation of the daily-average data for the full 

record and on a monthly basis. The “months” are defined to match the taking of 30-day 

raw materials sampling by participants and do not necessarily represent consecutive 

calendar days or calendar months. 

• The calculation of rolling 30 day average THC emissions 

• A tabular summary and graphical presentation of the 30 day average data. 

The emissions data are based on reported hourly emissions that have been screened to eliminate 

hours with missing data, invalid data (as coded by the kiln operator) and hours when the kiln is 

not in operation. While PCA has taken the position that startup, shutdown and malfunctions 

should not be included in the period covered by any THC limit, the hours involving kiln startup, 

shutdown, and malfunction have been retained in the record to be consistent with EPA’s 

proposal to include such hours when determining compliance with the standard. Daily average 

THC emissions are based on the operating hours surviving these screens. 

An initial tab labeled Summary has been provided to compile the basic statistics on THC 

emissions over the full length of record reported for each kiln. Kilns are coded according to the 

study design cell they fall into, the number of kilns the data represent (for cases where data from 

identical kilns are being reported), determinations of whether the kilns are commingled in the 

sense that term is used in the subcategorization study, and an indication of whether the kilns are 

area or major sources.

CEMS and FLS Data Used in Subcategorization Analysis

All of the CEMS data and the companion FLS raw materials testing results used in the statistical 

analysis of subcategorization of kilns are contained in the Excel spreadsheet: THC 

Subcategorization Analysis Database 2010.06.11.xls. This database reports monthly-average 

THC emissions, as determined from the CEMS data, matched to raw material outgassing results 

for composite feed and limestone samples for the same period, where those are available. The 

monthly CEMS data were obtained from the THC CEMS database, while the raw material 

outgassing reports were obtained from the reports prepared by FLS, the testing company. 

THC Combined Database

Daily-average THC data are available from multiple sources for some kilns and have been 

compiled into consolidated records of daily emissions in the Excel spreadsheet THC Combined 

Data 2010.06.13.xls. This database contains the emissions data used in the MACT floor analysis 

provided by PCA. The data come from the following three sources: 

• The daily emissions data in EPA’s docket for the Cement NESHAP proposed rule, 

• The extended series of daily emissions data compiled by PCA and submitted to EPA with 

comments filed in 2009. 

• The daily emissions data obtained in the THC subcategorization study. 

The THC “All Sources” tab presents the consolidated record for these kilns. 

The Summary tab in this database presents the consolidation of the THC CEMS record for all 

kilns for which we have data; this consolidated record was used in MACT floor calculations. 

For kilns with multiple sources of data, the entries in the Summary tab are drawn directly from 

tab THC All Sources. For other kilns, where daily emissions data are available only from the 

THC Study, the entries in the Summary tab are drawn from THC Study CEMS Database
