NOX SIP Call (Renewal)

This is a renewal of the Environmental Protection Agencys (EPAs) information collection request (ICR) addressing the burden and costs of information collection activities indirectly required under the NOX SIP Call (the Rule). The Rule requires affected states to include certain provisions in their state implementation plans (SIPs) addressing emissions of nitrogen oxides (NOX) that adversely affect air quality in other states. Previously, one of the Rules requirements applicable to all affected states was that the SIPs must include provisions requiring large electricity generating units (EGUs) and large non-EGU boilers and turbines to monitor and report their NOX mass emissions during the May-September ozone season according to the provisions of 40 CFR part 75 (referred to here as Part 75 monitoring requirements). In 2019, EPA amended the NOx SIP Call making the inclusion of Part 75 monitoring requirements in SIPs voluntary instead of mandatory, allowing states to submit SIP revisions to EPA requiring sources to perform other forms of monitoring. Although the Rule does not impose any requirements directly on sources, the Part 75 monitoring requirements were added to SIPs because of the Rule, and EPA has therefore submitted and periodically renewed an ICR to account for the information collection burden and costs of the Part 75 monitoring requirements imposed indirectly on sources. This ICR includes estimates of burden and costs both for sources subject to Part 75 monitoring requirements and sources performing other forms of monitoring for NOX SIP Call purposes under approved SIP revisions. Most large EGUs (and some large non-EGU boilers and turbines) affected under the NOX SIP Call are also subject to comparable Part 75 monitoring requirements under the Acid Rain Program (ARP) and/or the Cross-State Air Pollution Rule (CSAPR) trading programs. Both the ARP and CSAPR have approved ICRs (OMB Control Nos. 2060-0258 and 2060-0667), and this ICR accounts for information collection burden and costs only for sources that are not required to perform Part 75 monitoring under the ARP or CSAPR programs and whose information collection burden and costs therefore are not accounted for in the ARP ICR or the CSAPR ICR. This ICR also accounts for information collection burden and costs for additional sources primarily smaller EGUs that states voluntarily have made subject to Part 75 monitoring requirements under the SIPs they adopted for NOX SIP Call compliance, going beyond the Rules existing requirements. Under the NOx SIP Call, states are required to report certain data regarding emissions of sources in the state to EPA on an annual or triennial basis. The Air Emission Reporting Rule (AERR) for the national emission inventory includes very similar reporting requirements, and EPA believes that there is no material incremental information collection burden and cost associated with the required state reporting for NOX SIP Call purposes beyond the burden and cost estimates included in the AERR ICR (OMB Control Number 2060-0580). Thus, the only information collection burden and costs addressed in this ICR relate to the monitoring and reporting requirements imposed on sources through the states SIPs for compliance with the NOX SIP Call.

The latest form for NOX SIP Call (Renewal) expires 2029-09-30 and is listed under ICR 202505-2060-003.
