Network Overview The Clean Air Status and Trends Network (CASTNET) is a long-term multipollutant monitoring network designed to report trends in regional air quality including ozone (O3), oxidized and reduced forms of nitrogen, and sulfur. CASTNET fills an important role in the National Air Monitoring program by providing data in rural, disadvantaged communities that are often not monitored by the State and Local Air Monitoring Sites (SLAMS). CASTNET data are used to assess regional pollutant transport, validate and evaluate chemical transport models (e.g., CMAQ), and inform NAAQS reviews that consider human health and environmental impacts due to air pollution. CASTNET is managed collaboratively by the US Environmental Protection Agency - Clean Air Markets Division (EPA), the National Park Service - Air Resources Division (NPS), and the Bureau of Land Management - Wyoming State Office (BLM-WSO). In addition to EPA, NPS, and BLM-WSO, numerous other participants provide network support including tribes and other federal agencies, states, private landowners, and universities. The EPA contractor, WSP USA (WSP), operates the EPA-sponsored sites while the NPS and BLM-WSO contractor, Air Resource Specialists, Inc. (ARS), operates the remaining sites. A table detailing the management structure of CASTNET operations is provided in Figure 1. A summary of the entire CASTNET monitoring program is available online.1 US Government US Government Contractors EPA- Clean Air Markets Division WSP • • • • Project Officer QA Manager Technical Monitors Administrative Contracting Officer • Project Manager 0 Field Operations Manager 0 Laboratory Operations Manager 0 Data Management, Analysis, Interpretation, and Reporting Manager 0 Property Control Manager QA Supervisor 0 QA Manager • Contract Property Coordinator • NPS- Air Resources Division ARS • • Contracting Officer's Representative (COR) QA Coordinator • • Program Manager 0 Network Operations Manager 0 Data Management Manager QA Officer BLM - ¦ Wyoming State Office • Program Manager Figure 1. CASTNET Project Organization Eighty-four CASTNET sites measure weekly concentrations of sulfur dioxide (SO2), sulfate (SO42 ), nitrate (NO3), nitric acid (HNO3), ammonium (NhV), chloride (CI ) and base cations using a 3-stage filter pack (see Figure 2). Each site also reports hourly 9-meter temperature data to calculate local condition flow volumes. Eighty-one CASTNET sites collect ambient O3 concentrations, reported as hourly averages, using a dual cell, ultraviolet photometric analyzer. Eighty of the eighty-one CASTNET O3 monitoring analyzers meet the ambient monitoring and quality assurance requirements of Title 40, Code of Federal Regulations (CFR) Part 58 Appendices A, C, D and E. The ozone analyzer at Duke Forest, NC (DUK008) does not meet the siting criteria requirements from Appendix E of Part 58 because it has an inlet above the forest canopy at a height of 48 meters. Monitoring objectives, site types, detailed siting criteria, and other relevant parameters for each monitoring site may be found in Appendix A of this plan. In addition to weekly filter pack and hourly temperature and O3 measurements, forty-three CASTNET sites report other hourly meteorological parameters. CASTNET also measures trace-level NO/NOy, SO2, and CO at select sites. CASTNET O3 and trace-level gas monitors report hourly measurements throughout the entire year. Ozone analyzers are challenged nightly with known 1 CASTNET monitoring program https://www3.epa.eov/castnet/docs/CASTNET-Factsheet-2021.pdf Page 3 of 126 ------- concentrations delivered from the on-site transfer standard and trace gas analyzers are challenged every other night for fast- response troubleshooting. To monitor consistency between the agencies, EPA operates a co-located site (ROM206) at the NPS CASTNET site located in Rocky Mountain National Park, Colorado (ROM406). Also, EPA operates a pair of co-located O3 monitors (MCK131 and MCK231) in Mackville, KY with the co-located site identified as MCK231. Data from ROM206 and MCK231 are routinely analyzed to assess precision of the measurements and to identify biases that may arise. The CASTNET quality assurance (QA) program is independent of the program management. The QA program routinely assesses compliance with the CASTNET Quality Assurance Project Plan (QAPP)2 through internal monitoring, including audits and on-site system checks. Additionally, network QA is assessed through an independent audit program managed by EPA. Annual Performance Evaluation (PE) audits at most CASTNET sites are performed by Environmental Engineering & Measurement Services, Inc. (EE&MS). The remaining sites not audited by EE&MS receive PE audits by state, local, or tribal agencies to fulfill the annual PE audit requirement. EE&MS also assesses compliance with the CASTNET QAPP through a Field Systems Audit (FSA) at every CASTNET site every other year following protocols listed in the EPA QA Handbook.3 The FSA is a complementary component to the facility technical systems audit (TSA) performed by another independent auditor at both the EPA and NPS/BLM-WSO contractors' operations centers every third year. Both the EPA-sponsored and NPS-sponsored O3 monitoring programs began before 1990. While the NPS-sponsored O3 monitoring program was designed to meet O3 monitoring regulations from the beginning, the EPA-sponsored O3 monitoring program was not. All EPA-sponsored O3 monitors were upgraded by 2011 to comply with the requirements in 40 CFR Part 58. EPA replaced the existing O3 analyzers with a pair of Thermo Scientific™ Model 49i analyzers, where one analyzer has an onboard 03-generator for use as an on-site transfer standard. The upgrade of the EPA-sponsored O3 analyzers resulted in an improved ability to evaluate the quality of the ambient data. The EPA uses CASTNET O3 and trace-level gas data to calculate design values for all sites where data completeness requirements are met. The CASTNET program follows QA/QC procedures and schedules to meet the regulatory requirements detailed in Appendix B of this plan. This document includes an overview of the CASTNET regulatory O3 and trace-level gas monitoring program, a description of the internal and external QA programs, any planned changes to the network, and a description of each monitoring site. The procedures in this Network Plan originate from the requirements found in 40 CFR Part 58.10, but are adapted to a federally operated national monitoring network. 2 CASTNET Quality Assurance Project Plan v9.5 https://www3.epa.gov/castnet/docs/CASTNET_QAPP_v9-5_Main_Body.pdf 3 Quality Assurance Handbook for Air Pollution Measurement Systems Volume II, January 2017 https://www3.epa.gov/ttn/amtic/files/ambient/pm25/qa/Final%20Handbook%20Document%201_17.pdf Page 4 of 126 ------- © EPA Filterpack A EPA Small Footprint Filterpack © EPA Small Footprint Filterpack and Ozone ~ EPA Suspended Small Footprint Filterpack • EPA Filterpack and Ozone 0 NPS/EPA Co-located Pair with EPA Filterpack, Ozone, and Trace-level Gas <§> EPA Ozone - Suspended Filterpack ® NPS Filterpack, Ozone, and Meteorology • EPA Suspended Filterpack and Ozone (D NPS Ozone and Meteorology 0 EPA Filterpack, Ozone, and Meteorology E NPS Filterpack, Ozone, Meteorology, and Trace-level Gas ~ EPA Filterpack, Ozone, and Trace-level Gas ft NPS Ozone, Meteorology, and Trace-level Gas ¦ EPA Suspended Filterpack, Ozone, and Trace-level Gas © NPS Filterpack and Meteorology 0 EPA Filterpack, Ozone, Meteorology, and Trace-level Gas • BLM Small Footprint Filterpack, Ozone, and Meteorology EPA Co-located Pair with Filterpack and Ozone ~ BLM Small Footprint Filterpack and Meteorology EPA Filterpack, Non-Regulatory Ozone, and Trace-level Gas O NCore Participant Figure 2.

Ozone and Trace-level Gas Data CASTNET monitors measure ambient O3 concentrations for the entire year, which extends beyond the required O3 season for many states. CASTNET submits ambient concentrations in near real time to AIRNow4 and reports hourly data and nightly QC results to the CASTNET website daily for sites where EPA, NPS, or BLM-WSO is the primary quality assurance organization. NPS also displays O3 and meteorological data on the Gaseous Pollutant and Meteorological Data website5 and the BLM-WSO distributes O3 data through the Wyoming Air Resource Monitoring System (WARMS) website.6 WSP and ARS submit the O3 and trace-level gas concentrations to EPA's Air Quality System (AQS) database on a monthly basis and daily 1-point precision results on a quarterly basis. EPA submits O3 data from two co-located monitors (ROM206 and MCK231) to AQS, but these data are identified as 'NAAQS Excluded' because these data are solely used for QA purposes and are not used to calculate design values. CASTNET also measures ambient trace-level gas concentrations including SO2 and CO at Bondville, IL as required by the NCore program for the entire year. CASTNET reports ambient trace-level gas concentrations to the CASTNET website daily.7 WSP and ARS submit the hourly and 5-minute (SO2 only) trace-level gas concentrations to the AQS database on a monthly basis and daily 1-point precision check results on a quarterly basis. The trace-level gas measurements reported by EPA are certified for comparison against the respective NAAQS, while NPS does not certify their trace-level gas measurements. CASTNET uses the measurement quality objectives and criteria gas validation templates described in the EPA QA Handbook Validation Template8 (reproduced in Appendix B of this plan) to ensure that the highest quality data are being submitted to the AQS. These tables describe operational and systematic criteria for O3 and trace-level gas data validation, including requirements for frequency of measurements or audits, calibration schedules, and acceptance criteria for QC checks. One-minute data collected for ambient O3 and trace-level gas measurements are used for data validation purposes and are stored indefinitely. In addition to the QC checks required for meeting the measurement quality objectives and validation templates, semi-annual (O3) and quarterly (SO2 and CO) system checks are performed at each CASTNET site. Using National Institute of Standards and Technology (NIST) terminology, we define levels as degrees of separation from a NIST standard reference photometer (Level 1). During these checks, a field operations technician challenges the on-site analyzer and re-verifies the on-site transfer standard, calibrates the on-site analyzer to the traveling transfer standard (Level 2) as needed, and verifies the data logger and the shelter temperature probe using NIST-traceable standards. All on-site O3 transfer standards at CASTNET sites are NIST-traceable at Level 3. A flow chart diagram of the data certification process for the EPA contractor, WSP, is illustrated in Appendix D of this plan. Following guidance in 40 CFR Part 58.15, CASTNET federal managers from EPA, NPS, and BLM-WSO submit their annual data certification letter, including the AQS Data Certification Report (AMP600), to the EPA Office of Air Quality Planning and Standards (OAQPS) and applicable EPA Regional Offices by May 1 of each year. Consistent with 40 CFR Part 58.10 (a)(1), each analyzer included in Appendix G of this plan meets the siting and operational criteria required in appendices A, C, D, and E of 40 CFR Part 58 as identified for each year, except DUK008, as noted. 3. Exceptional Events Exceptional events are unusual or naturally occurring events that can affect air quality, but are not reasonably controllable using techniques that state, local, or tribal (S/L/T) air agencies may implement in order to attain and maintain the National Ambient Air Quality Standards. Exceptional events include wildfires, stratospheric ozone intrusions, and volcanic and seismic activities. Following guidance in 40 CFR Part 50.14(a)(1), a state may request that EPA exclude data that exceed the NAAQS and may have 4AIRNow https://www.airnow.gov 5 NPS Gaseous Pollutant and Meteorological Data website http://ard-request.air-resource.com/ 6 BLM-WSO WARMS website http://www.blmwarms.net/ 7 CASTNET website https://www.epa.gov/castnet/ 8 EPA QA Handbook Appendix D Validation Templates, March 2017 https://www3.epa.gov/ttn/amtic/files/ambient/pm25/qa/APP_D%20validation%20template%20version%2003_2017_for%20AMTIC%20Rev_ l.pdf Page 6 of 126 ------- been impacted by an exceptional event. As noted in the preamble to the 2016 Exceptional Events Rule (81 FR 68216, 10/3/2016),9 "as the single actor responsible for administering air quality planning and management activities within its jurisdictional boundaries, the state, exclusive of tribal lands, is ultimately responsible for submitting exceptional event demonstrations for exceedances that occur at all regulatory monitoring sites within the boundary of the state." CASTNET federal partners will work with S/L/T air agencies to include a flag in AQS for ambient data potentially influenced by an exceptional event, as requested by a S/L/T air agency that has jurisdiction over the area where a CASTNET site is located, and assist in preparing a demonstration (i.e., providing relevant information) if requested. The initial data flag is denoted as informational-use only and flagged data will continue to be used for NAAQS attainment purposes until the EPA Regional Administrator provides approval for an exceptional event demonstration. State agencies will be responsible for working with the EPA region to submit exceptional event demonstrations, which may include data from CASTNET sites. CASTNET managers do not have the authorization to determine the sufficiency of an exceptional event demonstration or whether CASTNET monitoring data should be excluded from the NAAQS calculation. S/L/T agencies should follow the regulations described in the revision to 40 CFR Parts 50 and 51, Treatment of Data Influenced by Exceptional Events (81 FR 68216,10/3/2016), to prepare and submit exceptional event demonstrations. To request that CASTNET managers apply initial data flags to CASTNET O3 data potentially impacted by an exceptional event, a S/L/T agency should email the following information to Timothy Sharac (sharac.timothvffiepa.gov) for EPA-sponsored sites, Barkley Sive (barklev sive@nps.gov) for NPS-sponsored sites, or Ryan McCammon (rmccammonffiblm.gov) for BLM-sponsored sites: o date/time range of incident, o type of exceptional event, and o CASTNET site(s) Initial data flags will be applied within 30 days after CASTNET managers receive a request from a S/L/T agency. Exceptional event types and their associated AQS qualifier codes are listed on the AQS Code List webpage.10 4. Network Audit Requirements The network audit requirements for 40 CFR Part 58 compliance are summarized in Appendix B of this plan. CASTNET managers include the PE and FSA schedules with each Annual Network Plan to ensure EPA Regional Offices have the opportunity to make travel arrangements if they choose to attend the audit. The EPA Regional Office contacts are listed in Appendix E of this plan. 5. Quality Control Checks Automated zero/precision/span (ZPS) quality control checks are performed nightly on all CASTNET ozone analyzers as shown in Table 1. EPA-sponsored ozone analyzers also receive additional weekly QC checks at 30, 90, and 150 ppb on Sundays to verify analyzer accuracy spanning typical ambient ozone concentrations. Additional checks may be initiated remotely to troubleshoot potential issues that may arise. The criteria for the automated ZPS QC checks are included in Appendix B of this plan. Zero, precision, and span QC results are posted to the CASTNET website daily for EPA-sponsored CASTNET sites. 9 Federal Register Volume 81, No. 191 October 3, 2016 https://www.epa.gOv/sites/production/files/2016-09/documents/exceptional_events_rule_revisions_2060-as02_final.pdf 10 AQS Code List webpage https://www.epa.gov/aqs/aqs-code-list Page 7 of 126 ------- Table 1 Quality Control Checks Frequency Os(ppb) S02(ppb) CO(ppb) Zero Daily 0 0* 0* Precision Daily 60 25* 500* Span Daily 225** 90* 1800* Additional point #1 Weekly 30*** 5*** * * * O 00 Additional point #2 Weekly gO*** 40*** 300*** Additional point #3 Weekly 150*** 60*** 800*** Table 1 Notes: *S02 and CO checks are performed every other night **NPS and BLM-WSO perform 03 span checks at 200 ppb ***EPA-sponsored CASTNET sites 6. Performance Evaluations (PE) In accordance with EPA's QA Handbook and 40 CFR Parts 53 and 58, an independent auditor performs an annual PE audit and submits these results to AQS on a quarterly basis. Verification of the O3 and trace-level gas analyzers during the field systems audit (FSA) requires that the zero/span be within ±2% of the full scale of the best fit linear line. The auditor selects target concentration values among the ten audit levels, as described in Appendix A to 40 CFR Part 58.11 The evaluation is made by challenging the analyzer with audit gas standards of known concentration from a minimum of three audit levels that represent routine concentrations at the monitoring site (see Table 2 for acceptable audit ranges). Results for audit levels 1 and 2 must be less than ±1.5 ppb or less than ±15.1%, whichever is less restrictive, to meet the acceptance criteria for O3, SO2, and NO2, while levels 1 and 2 must be less than ±0.031 ppm or less than ±15.1%, whichever is less restrictive, to meet the acceptance criteria for CO. Results from levels 3-10 must be less than ±15.1% to meet the acceptance criteria.

The proposed PE and FSA audit schedule for CASTNET sites is shown in Table 3 below. The independent auditor uses equipment that is NIST-certified (verified twice per year) to audit CASTNET monitoring equipment. The independent auditor performs a PE audit at each site annually and performs an FSA which includes an audit of flow, meteorological sensors, and related parameters every other year. States may perform a PE audit if they coordinate with the sponsoring agency, site supervisor, and independent auditor as explained in the third-party CASTNET audit document.12 11 40 CFR Part 58 Appendix A - Quality Assurance Requirements for Monitors used in Evaluations of National Ambient Air Quality Standards. https://www.ecfr.gov/cgi-bin/retrieveECFR?n=40y6.0.1.1.6 12 CASTNET third-party audit document https://www.epa.gov/sites/production/files/2015-07/documents/third_party_audits.pdf Page 8 of 126 ------- Table 3 Proposed PE and FSA Schedule EP, Rgi State AQS ID POC SITE ID Site Name Audit Type Audit Month Audit Type Audit Month Even Years Even Years Odd Years Odd Years 1 CT 090159991 1 ABT147 Abington FSA + PE October PE September 1 ME 230090103 1 ACA416 Acadia NP FSA + PE October Performed by ME-DEP September 2 NJ 340219991 1 WSP144 Wash.

Field Systems Audit (FSA) An independent auditor performs a field systems audit (FSA) every other year at each CASTNET site to complement the requirements of a technical systems audit (TSA) which is required every three years to ensure network-wide consistency among all sites within CASTNET. The purpose of an FSA is to provide an independent assessment of the siting criteria, performance of monitoring equipment, and the proficiency of the site operator. The auditor verifies that filter pack flow, the O3 analyzer, shelter temperature, and the meteorological sensors meet the acceptance criteria listed in Appendix B and the CASTNET QAPP.13 The auditor also completes a PE audit for O3 in addition to an FSA to verify there are no line losses within the system and documents whether the monitor configuration violates any of the CASTNET siting criteria found in the CASTNET QAPP. During an FSA, the auditor discusses any issues related to equipment, siting criteria, or operator handling with the operator and/or site supervisor. The independent auditor submits audit results to the site supervisor, site operator, site funding agency, and CASTNET contractor following the audit. A summary of audit results is available in a quarterly report and posted to CASTNET's Independent Audit Program webpage.14 The independent auditor sends FSA announcement letters to the agency contractor, site operator, and site sponsor describing the purpose of the site visit 2-4 weeks prior to an FSA to ensure all parties involved are prepared. The current proposed schedule is shown in Table 3. 8. National Performance Audit Program (NPAP) The purpose of the NPAP is to assess the proficiency of the monitoring organization. As the primary sponsor for CASTNET, EPA's Clean Air Markets Division coordinates with OAQPS, EPA Regional Offices (listed in Appendix E of this plan), and the Environmental Services Assistance Team (ESAT) to fulfill the NPAP requirements for all CASTNET sites. Each monitoring organization's network is required to complete NPAP audits, with a goal of 20% of the sites each year or 100% within 6 years. Through-the-probe audits are performed during an NPAP audit using a zero air generator to supply the carrier gas to an O3 generator. Audit O3 concentrations are delivered to the through-the-probe dual glass manifold connected to the monitor's inlet probe while venting excess flow to the atmosphere. The O3 generator is referenced back to a Level 2 O3 standard which is in turn referenced to a Level 1 standard reference photometer. The auditor selects 3 or 4 known target concentrations to determine the accuracy of the on-site O3 analyzer. The O3 NPAP audit's percent difference criterion of less than ±1.5 ppb at audit levels 1 and 2 and less than ±10.1% at audit levels 3 through 10 is more rigorous than the criteria used for the annual performance evaluations in Table 2. The NPAP auditor is responsible for submitting the audit results to AQS. NPAP audits are also performed on CO and SO2 analyzers, when present. 9. Technical Systems Audit (TSA) CASTNET uses an independent auditor to conduct the facilities portion of the TSA requirements at the contractor's O3 laboratory once every three years. The purpose of the facility TSA is to provide a qualitative appraisal of the total measurement system. Site planning, organization, documentation, and operation are evaluated to ensure that good QA/QC practices are being applied throughout the monitoring program. An outline of the facility TSA is available in Appendix F. RTI International performed facility TSAs at the WSP laboratory in Newberry, FL in 2012, 2015, and 2018 and at the ARS facility in Fort Collins, CO in 2013, 2017, and 2021. Results, findings, and the responses to the findings can be found on the CASTNET documents webpage15 under "Technical Systems Audit." 13 CASTNET Documents webpage https://www.epa.gov/castnet/ 14CASTNET's Independent Audit Program webpage https://www.epa.gov/castnet/independent-audit-program 15 CASTNET Documents webpage https://www.epa.gov/castnet/ Page 11 of 126 ------- 10. Annual Monitoring Network Plans and Network Assessment CASTNET staff prepare an annual CASTNET Network Plan for public review. The Network Plan focuses on the CASTNET O3 and trace-level gas monitoring program and addresses the monitoring requirements of 40 CFR 58.10(b). EPA, NPS, and BLM-WSO consult with OAQPS and applicable EPA Regional Offices ahead of adding or discontinuing O3 monitors in accordance with 40 CFR 58.14 and any known changes are included in this Network Plan. CASTNET staff collect additional comments by sending draft copies to the National Association of Clean Air Agencies (NACAA) and the Association of Air Pollution Control Agencies (AAPCA). A draft copy is also distributed through OAQPS' monitoring list-serve. CASTNET staff contact states directly if these states use a CASTNET monitor in place of a state operated O3 monitor (e.g., SLAMS) to ensure their participation in the planning process. CASTNET staff submit a final version of the Network Plan and responses to any comments received on the draft Network Plan to the EPA CASTNET O3 webpage16and OAQPS' Ambient Monitoring Technology Information Center (AMTIC) Network Plans webpage.17 The schedule for these activities is outlined in Table 5. The Division Director or a designee at the EPA's Clean Air Markets Division approves this plan with input from the public by July 1. OAQPS provides comments within 120 days on any plans proposing changes to the O3 network. Table 4 Annual Network Plan Schedule Date Network Plan Steps May 16 Distribute draft Network Plan to OAQPS, OAQPS list-serve, EPA Regional Offices, NACAA, AAPCA and post for public review on the CASTNET webpage June 16 Deadline for public comments to draft Network Plan June 30 CASTNET staff complete response to public comments July 1 CASTNET staff distribute final version of Network Plan October 31 OAQPS/Lead EPA Regional Office review Network Plan and provide approval EPA completes a network assessment every 5 years in accordance with 40 CFR 58.10(d). CASTNET staff post the network assessment to the EPA CASTNET O3 webpage16 and OAQPS' AMTIC Network Plan webpage.17 There is no public comment review and response to this document. The next assessment is due July 1, 2025, and every 5 years thereafter. Some states include CASTNET sites in their Network Plan to fulfill their monitoring requirement under 40 CFR Part 58 Appendix D. These states should notify the CASTNET agency sponsor that they will be using the CASTNET site in their plan so that the state may be included in any discussions related to changes at the site. 16 CASTNET Os webpage https://www.epa.gov/castnet/castnet-ozone-monitoring 17 OAQPS' AMTIC Network Plans webpage https://www.epa.gov/amtic/state-and-local-monitoring-plans Page 12 of 126 ------- 11. Network Modification As of May 2023, the following network modifications occurred or are planned: • On May 10, 2022, the United States Environmental Protection Agency (EPA) suspended monitoring at 11CASTNET sites due to budget constraints. See Appendix K for a list of sites where data collection was suspended. Sites were "mothballed" rather than decommissioned to allow the Agency to review the current status of the network and resume sampling if funding was made available. • EPA's Office of Atmospheric Protection (OAP) requested a scientific review of the CASTNET program and its contribution to the National Atmospheric Deposition Program (NADP). The review is a public process managed by EPA's Science Advisory Board (SAB) and a panel of experts that have been asked to advise the Agency on the scientific merits of the programs. The review panel will consider options for CASTNET under the current budget constraints while meeting EPA's strategic objectives, as well as evaluate new and emerging scientific and policy questions that could be addressed by CASTNET. • OAP will use the report provided by the SAB review panel, public comments, and information gathered from stakeholders and partners to design a more robust CASTNET program that meets the current annual operating budget requirements. • On October 1, 2022 Santee Sioux (SAN189, 31-107-9991 POC 1) resumed filterpack measurements. • Monitoring at the Alhambra, IL CASTNET site (ALH157,17-119-9991 POC 1) was discontinued on December 6, 2022 due to the loss of the land lease. A new location has been identified and sampling may resume if funding allows. • Filterpack measurements at Wind Cave National Park (WNC429, 46-033-0132 POC 3) were discontinued on December 27, 2022. • With support from EPA Region 9 and Office of Air and Radiation (OAR), CASTNET added the 8th Tribal site in partnership with the La Posta Band of Diegueno Mission Indians of the La Posta Indian Reservation, California (La Posta). The small- footprint site with a regulatory ozone monitor was installed in January 2023 in eastern San Diego county (LPO010, 06- 073-9991 POC 1). • A Nafion drier was installed on the co-located, QA-only O3 monitor (MCK231, 21-229-9991 POC 2) in Mackville, KY on March 14, 2023 to assess any biases introduced. The primary monitor (MCK131, 21-229-9991 POC 1) is continuing to operate without a Nafion drier. • Petrified Forest (PET427, 04-017-0119 POC 1) is scheduled to end sampling by December 31, 2023 due to the recent discovery of Native American artifacts near the monitoring shelter. 12. Data Reporting and Certification CASTNET staff submit applicable ambient and quality assurance data to AQS within 90 days after the end of each quarterly reporting period. CASTNET complies with the annual air monitoring certification requirements in accordance with 40 CFR 58.15- 16. EPA, NPS, and BLM-WSO certify CASTNET ambient O3, SO2, and CO data and quality assurance results by May 1 for the prior calendar year for their respective CASTNET sites and submit the data to OAQPS for review.
