I think the compliance date for those requirements would require an opinion from OECA because we do specifically call out "compliance dates" in the section that discuss calibrations for feed or clinker rates, though we don't call then by that name. But we also say three years f or all requirements in the compliance date section. However, we think that there is enough interpretative leeway in the term calibration that this should not cause a problem in the near term. It does need to be addressed with some of the other testing an d mo nitoring issues. And we are not comfortable with addressing this in the clarification notice. It would be better addressed through notice and comment rulemaking. Keith W . Barnett USEPA/OAQPS/SPPD/MMG Mail Code D243

Keith, Thank you. The last part of your message is a bit confusing. Is it in reference to my question about the clinker production monitoring issues? Is it safe to assume that the deadline for compliance with these requirements is 9

Subject: RE: Cement Correction Notice I think I sent the wrong table. Here is the corrected version. (See attached file: Table 2.docx) Steve Silverman and I discussed this issue w ith Hector. (W e called Hector because he was the first person to raise the issue and had already sent information). As a result of that conversation Steve and I believe this can be dealt with as more of an interpretative issue as to the meaning of calibra tion, and don't believe is would be a good idea to try and address this in the technical correction notice.

Keith, Thank for the opportunity to review. Table 2 is still missing the opacity standard (20) under items 1 and 2. Otherwise, the preamble and rule text are clear to me. Do you plan to also clarify the complian ce deadline language addressing the clinker productionmo nitoring provisions in Sections 63.1350(d)(2) and 60.63(b)(2)?

Thanks, And y
