EPA explained that because of insufficient data, they are considering
issuing a 114 request to selected Portland cement plants to conduct
additional HCl testing using method 321. Data are needed for 10 – 20
kilns. EPA would probably issue the request the week of February 1st.
The industry expressed concerns due to the time and cost involved in
additional testing as well as the fact that some of the kilns targeted
were not operating.

The use of data below the detection limit was discussed as well as the
distinction between a detection limit and the practical quantification
limit.

The problem of testing on monovent baghouses was raised by PCA. EPA
stated that where testing would be difficult, the company could test at
a different kiln or plant.

PCA members will meet to discuss EPA’s HCl data needs and get back to
EPA.
