Owners/operators of affected phosphoric acid manufacturing and phosphate fertilizer production must submit one-time only notifications (where applicable) and annual reports on performance test results. Semiannual reports are required. In addition, a quarterly report is required when excess emissions occur.
Subparts AA and BB require respondents to install monitoring devices to measure the pressure drop and liquid flow rate for wet scrubbers. These operating parameters are permitted to vary within ranges determined concurrently with performance tests. Exceedances of the operating ranges are considered violations of the site-specific operating limits.
The standards require sources to determine and record the amount of phosphatic feedstock material processed or stored on a daily basis. Respondents also maintain records of specific information needed to determine that the standards are being achieved and maintained.
On behalf of this Federal agency, I certify that the collection of information encompassed by this request complies with 5 CFR 1320.9 and the related provisions of 5 CFR 1320.8(b)(3).
The following is a summary of the topics, regarding the proposed collection of information, that the certification covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control number;
If you are unable to certify compliance with any of these provisions, identify the item by leaving the box unchecked and explain the reason in the Supporting Statement.
