Hi Cortney,

Regarding your question below, the piece missing is the * * * * *. We believe that piece
was in there at one time and was d eleted inadvertently. Anyway, paragraph (v) is unchanged from original rule, so the reg text here should skip over (v) to (vi) using the * * * * *. Attached is revised preamble/rule with that edit on page 129.

Let us know if you have additional qu estions.

Thanks.

Chuck

Did y’all catch this in Friday’s version and correct in today’s? I haven’t taken a look yet.

There is a potential numbering error on bottom page 126 and top of 126. Paragraphs go from (i v) to (vi) skipping (v).

(iv) Not allowing the mass rate of total chromium in the exhaust gas stream discharged to the atmosphere
to exceed the maximum allowable mass emission rate determined by using the calculation procedure in §63.344(f)(1)(i) for a ll enclosed hard chromium electroplating tanks that are existing affected sources and are located at large hard chromium electroplating facilities; or (vi) Not allowing the concentration of total chromium in the exhaust gas stream discharged to the

atm osphere to exceed 0.006 mg/dscm of ventilation air (2.6 × 10?6 gr/dscf) for all enclosed hard chromium electroplating tanks that are new affected sources; or(vii) Not allowing the mass rate of total chromium in the exhaust gas stream discharged to the atmosphere
to exceed the maximum allowable mass emission rate determined by using the calculation procedure in §63.344(f)(1)(iii) if the enclosed hard chromium electroplating tank is a new affected source. (viii) After [INSERT DATE 3 YEARS AFTER PUBLI CATION OF FINAL RULE IN THE FEDERAL REGISTER], the owner or operator of an affected enclosed hard chromium electroplating tank shall not
add PFOS

- based fume suppressants to any affected enclosed hard chromium electroplating tank.

Hi Cortney,

As we discussed, attached is a revised preamble/rule which addresses remaining comments a nd edits. One version shows changes in "track changes", the other is a clean version.

Let me know if you have questions.

Thanks.
