Guam EPA’s Karl Olson Retires After 22 Years of Service

May 4, 2018 (Tiyan, Guam) — Guam EPA Environmental Health Specialist III Karl Olson has retired from service with the agency’s Pesticides Enforcement Program. In recognition and celebration of his retirement, a ceremony was held to honor Mr. Olson and to wish him a happy retirement. Mr. Olson received a legislative resolution from Senator Frank Blas Aguon Jr. and Vice Speaker Therese Terlaje. In addition, Mr. Olson also received special recognition from the United States Environmental Protection Agency and the Environmental Stewardship Award from Guam EPA. The special recognition and environmental stewardship award was presented by Mr. Bob Perron, Chairman of the Guam EPA Board of Directors.

The agency’s Administrator, Walter S. Leon Guerrero, and Deputy Administrator, Yvette L.G. Cruz conveyed the following to Mr. Olson at the retirement ceremony: “English author Douglas Adams once said, ‘To give real service you must add something which cannot be bought or measured with money, and that is sincerity and integrity.’ These words truly echo the character of anyone who engages in public service, most especially within a regulatory agency. Mr. Karl Olson’s distinguished career with the Guam Environmental Protection Agency began in 1996 as an Environmental Technician. Mr. Olson would go on to progress through the agency rungs as an Inspector I and Inspector II in the agency’s Water Resources Program and then ultimately as an Environmental Health Specialist in the agency’s Pesticides Enforcement Program. Mr. Olson’s career has been marked by acclamations from the United States Environmental Protection Agency’s Region IX Office and the Government of Guam as a recipient of the MagPro Customer Service Team Excellence award in 2012 and as Environmental Health Division Employee of the Year for in 2014. While Mr. Olson’s knowledge, work ethic and positive demeanor will be missed in the agency, we remain beholden to the knowledge he has shared with us, and his efforts in effectuating meaningful changes with inspection protocols, pesticide enforcement policy, safety, and training and overall program development. On behalf of our agency, we are honored to wish Mr. Olson the very best of luck in the future, with all of the fruitful blessings that God can bestow upon him and his family. Un dĂ„ngkolu na si Yu’us Ma’Ă„se for 22 years of service to our island!”

U.S. Army Corps of Engineers to promote “Recognize. Retreat. Report.” on Guam

April 13, 2018 (Tiyan, Guam) — Officials from the United States Army Corps of Engineers (USACE) are on island to conduct an explosives safety outreach program known as “3Rs: Recognize. Retreat. Report.” This is the result of collaboration between the Guam Environmental Protection Agency’s (Guam EPA) Green Parcels/Defense and State Memorandum of Agreement (GP-DSMOA) division and USACE to promote safety and ensure that residents and visitors practice the proper safety measures in the event that they discover munitions and explosives of concern (MECs).

Guam EPA Administrator Walter S. Leon Guerrero stated, “Guam EPA is pleased to be collaborating with both the USACE and the Guam Homeland Security Office in spreading the ‘3Rs’ message that urges all of us to recognize, retreat and report.”

The presence of MECs on Guam has been well documented and established since the conclusion of the Japanese occupation and World War II. Leon Guerrero also added, “The Offices of Guam Homeland Security and Civil Defense have been at the forefront of sharing information, tips and preparedness planning in the event that manmade or natural disasters should occur on Guam. We are proud of the partnership that we have with their office for the 3Rs approach.”

Guam Homeland Security Advisor, George Charfauros adds, “The 3Rs approach is a good opportunity to create general awareness for the community about munitions and explosives of concerns. Response personnel are called for unexploded ordnances (UXO) found in areas around the island, oftentimes from WWII era. While these seem old and interesting; when found, it is important to know basic recognition techniques and the proper avenue to report these findings.”

If MECs or UXOs are found, the immediate action is to retreat and report the finding to the proper authorities, including local law enforcement.

Representatives from USACE have scheduled two outreach efforts to promote their 3Rs outreach campaign on Guam. USACE will be available this evening at the 2018 Smokin Wheels Racing event at the Guam International Raceway. USACE representatives will be onsite for the duration of the three-day event. Residents and visitors will also be able to interact with USACE once again at the Ninth Annual Banana Festival at the Ipan Beach Park from April 19 – 22, 2018

Leon Guerrero further stated, “Just as we have an entire generation that has not experienced a category 3 or category 4 storm, we also have an entire generation that may not possess the proper understanding of the prevalence or the dangers of MECs. The 3Rs approach looks to eliminate a potential pitfall and bolster local efforts to protect human and environmental health.”

NEWS: Guam EPA Recognizes Radon Action Month, completes new radon lab installation

January 23, 2018 (Tiyan, Guam) — The Guam Environmental Protection Agency (Guam EPA) has completed the installation of its new radon testing laboratory. The lab features the latest in radon detection technology married with sustainable software and hardware enhancements that will bring Guam’s radon testing capability to the forefront and on par with our national counterparts. Proficiency performance testing and calibration for the lab have been completed this month with the assistance of Dr. James F. Burkhart, physics professor at the University of Colorado, Colorado Springs, Colorado and director of the Western Regional Radon Training Center established by the U.S. Environmental Protection Agency. Guam EPA looks to obtain certification for the agency radon lab in March.

Radon is a radioactive, tasteless, colorless and odorless gas that forms from the natural decay of certain elements in rocks and soil. As a result of this decay, radon gas is emitted into the atmosphere and can seep into home and office buildings. Radon is classified as a carcinogen and long-term radon exposure has been linked to lung cancer. Radon levels are measured in “picoCuries per liter (pCie/L)” and the action level for mitigation in your home or office is 4pCie/L of air.

“Radon Action Month” is traditionally recognized in January. This year, Guam EPA acknowledged Radon Action Month with a proclamation signing ceremony with Lieutenant Governor Ray Tenorio at the Governor’s Complex in Adelup on January 23, 2018. Radon Action Month is a national campaign that aims to raise awareness about the dangers of radon in the home and office and how mitigation techniques can be implemented to reduce the amount of radon exposure. According to the USEPA and the Surgeon General’s Office, radon is the second leading cause of lung cancer in the United States, just behind tobacco smoking. Statistics show that radon related lung cancer claims some 24,000 lives annually – claiming more lives than drunk driving and drowning.

Guam EPA Administrator Walter S. Leon Guerrero stated, “Previous studies conducted by our agency have shown that radon is problem on Guam and that testing your home or office is the only way to determine radon levels.” Leon Guerrero also adds, “We are pleased to be working with USEPA’s Indoor Radon Program and we are grateful for the funding that Guam EPA has received through our consolidated grant to outfit our lab. We look to continue to enhance our service to the public through this lab.” Additional support for the Guam EPA’s radon lab has also come by way of a memorandum of agreement between the agency and the University of Guam. Testing for radon in your home or office is easy and inexpensive and should be done at least once every five years. The type of mitigation that is required to reduce radon exposure in the home or office depends on the current radon level in the structure.

Guam EPA is conducting beta testing and staff development in order to ensure efficiency for residents who wish to have the agency test their homes for radon. Guam EPA will inform the residential community when the service will be available once the outreach phase is finalized.

For more information about radon testing and mitigation on Guam, please contact the Guam EPA Air Program Supervisor, Roland Gutierrez by telephone at 671-300-4751 or via email: roland.gutierrez @epa.guam.gov

NEWS: Guam EPA reports 32.34% recycling rate – up 3.34 points

15 November 2017

November 15, 2017 (Tiyan, Guam) — The Guam Environmental Protection Agency (Guam EPA) reports a 32.34% recycling rate for all eligible discarded materials in calendar year 2016. This represents an increase of 3.34 percentage points to last year’s reported recycling rate of 29%. Data collection for the recycling rate has been analyzed and calculated based on reported figures from our island’s permitted waste disposal and recycling facilities since 2011. Guam EPA first reported a recycling rate of 17.85% in 2012, representing over 29,000 tons. Discarded materials that are ineligible for data collection towards the recycling rate include: construction and demolition debris, bio-solids and vehicles.

Guam EPA has historically released the island’s recycling rate on “America Recycles Day.” This year, Guam EPA celebrated America Recycles Days with a proclamation signing ceremony with Lieutenant Governor Ray Tenorio at the Governor’s Complex in Adelup. America Recycles Day is a national campaign that aims to raise awareness about the benefits of recycling and buying products made with recycled materials. According to the United States Environmental Protection Agency, the national recycling rate in the United States is 34%.

Guam EPA Administrator Walter S. Leon Guerrero stated, “In recognition of America Recycles Day, our agency is pleased to report that over 47,000 tons of waste has either been recycled or mulched and composted and will never find a way into our landfill.” Discarded materials that are eligible for data collection include: cardboard, mixed paper, e-waste, ferrous and nonferrous metals, tires, automotive batteries, plastics, mulched and composted material. Leon Guerrero also adds, “With this rising trend in materials that are recycled or reused, Guam is on a great path towards our goal of the zero waste.”

Guam EPA has observed that some factors can affect our island’s recycling rate. Global market value on certain recyclables can adversely impact the export on certain recyclable commodities. Positive contributions towards the recycling rate include promoting awareness in promoting reduction in the waste stream in the community through public and private sector involvement, active participation with our youth groups in the collection of discarded materials around the island and curbside recycling programs.

This year’s statistics revealed significant increases in the following categories:
