The Environmental Protection Agency Region 2 awarded the Puerto Rico Department of Natural and Environmental Resources $437,763 on July 1, 2026, under the Surveys, Studies, Research, Investigations, Demonstrations, and Special Purpose Activities Relating to the Clean Air Act program (CFDA 66.034) to operate and maintain Puerto Rico's fine particulate matter (PM2.5) air quality monitoring network and collect representative air quality data.

The recipient will conduct ambient air quality sampling, collect PM2.5 monitoring data, and quality-assure the measurements for dissemination to the public via EPA's AirNow website, the territorial government website, and other media outlets. The work includes gathering information on particle composition in Puerto Rico's air to support planning for PM2.5 exposure reduction strategies. The monitoring network generates near-real-time data benefiting Puerto Rico's citizens.

The period of performance runs from July 1, 2026, through June 30, 2027, with all work performed in Puerto Rico. The award carries no sub-recipients.

This agreement provides continued assistance to the puerto rico department of natural and environmental resources (PR dner) to operate and maintain its air quality monitoring network and to measure the levels of very fine particulate matter. This work will involve air quality sampling and generation of representative air quality data. This agreement provides funding to the puerto rico department of natural and environmental resources to assist with necessary development, establishment, and maintenance of adequate monitoring programs for the prevention and control of air pollution or implementation of national primary and secondary air quality standards. This grant is provided to conduct ambient air quality monitoring of fine particulate matter (PM2.5). Specifically, the recipient will conduct air quality sampling and generation of representative air quality data. Activities:the activities include focusing on the operation and maintenance of puerto rico's PM2.5 monitoring network. Air quality data will be collected, and experience and other knowledge will be obtained regarding PM2.5 air quality and sampling equipment. Subrecipient:no subawards are included in this assistance agreement.outcomes:the anticipated deliverables include the operation and maintenance of the PM2.5 network, ensuring that PM2.5 air quality data is collected and quality assured. The expected outcomes include providing near real time data, primarily for the purpose of reporting this information to the public via EPA's airnow web site, the state's web site, and various other media outlets. This project also provides data on the make-up of the particles found in puerto rico's air to assist planners in developing strategies to reduce PM2.5 exposure. The intended beneficiaries include the citizens of puerto rico.
