CPSC Staff Continues to Work With NIOSH. EPA and NIST

The National Institute for Occupational Safety and Health (NIOSH) is continuing a multiyear project
assessing toxicological responses to aerosolized emissions from fused deposition modeling (FDM) 3D
printers. The Phase 2 studies are continuing with a focus on (1) characterizing emissions from
acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) filaments with other types of engineered
nanoparticles (other than multiwalled carbon nanotubes—MWCNTs); (2) investigating pulmonary and
microvascular responses, liver toxicity and neurotoxicity, as well as the biodistribution and
biopersistence of emissions, after inhalation of polycarbonate (PC) filament emissions in rats;
(3) evaluating responses in a murine experimental model of asthma; and (4) evaluating the toxicological
effects on the reproductive system after exposure to PC filament emissions in vitro using commercially
available human placental cells (Farcas et al. 2022).

Work continues on the NIOSH-EPA collaborative project that evaluates several 3D printers during
operation and during feedstock recycling tasks to understand factors that influence release of emissions.
Specifically, the aims of this project are to evaluate the influence of fused filament fabrication (FFF) 3D
printer design, FFF feedstock filament and recycling of plastics to make filament and FFF 3D printing with
recycled filaments. Furthermore, NIOSH is using the information generated from these studies for
outreach publications, recognizing the concern for exposures in public and work spaces (Stefaniak 2021,
Stefaniak 2022).

EPA is continuing a multiyear collaborative project with NIOSH on characterizing commercially available
and commonly purchased FDM filament materials and quantifying the composition and release of
organic and inorganic chemicals and materials from FDM printer filaments, waste and printed objects.
The Phase 2 and Phase 3 studies continue, including identification of post-print-processing procedures
for various FDM filament materials; compositional characterization of products and/or waste materials
created from the printing process, as well as substances released from printed products and post-print-
modified products under relevant and intended use conditions for the product lifecycle
(e.g., microplastic and nanoplastic content); and the determination of product fragility under
foreseeable use scenarios.

The National Institute of Standards and Technology (NIST) continues its project on performing a long-
term (multiweek) release, accumulation and continuous monitoring study using multiple consumer-
grade 3D printers to support downstream exposure assessment.

With the broad federal agency interest in exposure to 3D printer material components and emissions,
the National Nanotechnology Coordination Office has proposed including 3D printers in its nanoEHS
strategy.

Portable Generator Safety

Project Contact: Janet Buyer, 301-987-2293, ibuver(a)cDsc.aov
Background

In November 2016, the CPSC voted to approve a notice of proposed rulemaking (NPR) to reduce the risk
of carbon monoxide (CO) poisoning deaths and injuries associated with portable generators. The
proposed rule limits portable generator CO emission rates. The proposed rule's CO emission rates are
expected to lower the CO emission rate from that of current generators by 90 percent. This is achievable
using existing and proven emission-control technologies already in the marketplace. The docket number
is CPSC-2006-0057, and the Federal Register weblink is available here:

https://www.federalregister.gov/documents/2016/ll/21/2016~26962/safetv-standard~for-portable-
generators.

CPSC staff has been participating in voluntary standards development. On January 24, 2018,
Underwriters Laboratories (UL) announced that UL 2201 had received ANSI approval
(https://www.ul.com/portablegenerators). This standard has a requirement for a reduced CO emission
rate of 150 g/hr and a shutoff when CO concentrations around the generator (1 foot above the center of
the top surface of the portable generator) reach either an instantaneous reading of 400 parts per million
(ppm) or a rolling 10-minute average of 150 ppm. On April 20, 2018, in a separate voluntary standard by
the Portable Generator Manufacturers Association (PGMA)—G300 standard, Safety and Performance of
Portable Generators—also received ANSI approval. This standard has a requirement for a CO sensing
shutoff system that will shut off the generator when CO concentrations around the generator (1-2
inches above the center of the top surface of the portable generator) reach either an instantaneous
reading of 800 ppm or a rolling 10-minute average of 400 ppm.

CPSC has an interagency agreement with NIST to estimate the effectiveness of the CO hazard-mitigation
requirements in these standards. The plan for this evaluation is published in NISTTN 2048 (available
online at http://dx.doi.org/10.6028/NIST.TN.2048). The plan was open for public comment from July 9,
2019, to September 9, 2019. CPSC and NIST evaluated the comments and revised the plan before
execution. An additional report, NISTTN 2049 (http://dx.doi.org/10.6028/NIST.TN.2049). was published
at the same time as the plan. This report documents testing that was done on generators that were shut
off using the shutoff criteria in both voluntary standards.

CPSC and NIST evaluated the comments on NIST Technical Note 2048, and, on August 12, 2020, CPSC
published a memorandum that documents the revisions to the plan, as well as staffs summaries of all
the comments and staffs responses. The memorandum, titled Revisions to the Plan Documented in NIST
technical Note 2048: Simulation and Analysis Plan to Evaluate the Impact of CO Mitigation Requirements
for Portable Generators, can be found at https://www.cpsc.gov/s3fs-public/revisions-to-TN2Q48-and-

New Updates

Staff completed their evaluation of the effectiveness of the voluntary standards and documented the
results in a briefing package delivered to CPSC in February 2022, available at https://www.cpsc.gov/s3fs"
public/Briefing-Package-on-Portable-Generator-Voluntary-

Standards.pdf?Versionld=hLnAkKQ6bCD SKin8RE6lax.BiZsB5x3. The staff analysis concluded that the CO
mitigation requirements in UL 2201 are more effective than those in PGMA G300-2018. UL 2201 would
avert nearly all the deaths and result in relatively few of the survivors sustaining injuries from the
reduced CO exposure, compared to PGMA G300-2018 averting about 87 percent of the deaths and
resulting in more of the survivors sustaining injuries from the CO exposure that occurred. Staff also
found that there was low compliance with the voluntary standards. Staff is now preparing a rulemaking
briefing package for delivery to CPSC in fiscal year (FY) 2023.

Voluntary Standards Related to IAQ

Project Contact: Jacqueline Campbell, icampbell(S)cDsc.aov
Background

Every year, CPSC is involved in several dozen voluntary standards activities with standard development
organizations. Twice a year, CPSC publishes an update on its voluntary standards activities. A subset of
standards focuses on the relationship between certain consumer products and IAQ. Standards focus on
methods to directly measure products, emissions from products or concentrations of chemicals in the
indoor environment, as well as managing emissions from products.

New Updates

The list below provides product areas where standards development work related to IAQ is underway,
should soon start or was recently completed:

•	Additive Manufacturing/3D printing

•	Candles and Candle Accessories

•	CO Alarms

•	Gas Ranges

•	Nanotechnology

•	Portable Generators

•	Spray Polyurethane Foam Insulation

CPSC is also leading an effort to develop a guide to define and categorize modeling approaches to
support source characterization for indoor exposure assessment of many different kinds of consumer
products. This is work item WK80812 under ASTM D22.05 (the Indoor Air subcommittee).

New Updates

CPSC is working with RTI to complete a market-use report for PFAS substances used in consumer
product applications. The report is expected in the fourth quarter of FY 2023.

Gas Ranges—Request for Information

Project Contact: Scott Ayers, saver$(S)cDsc.aov
Background

CPSC has been working with stakeholders for a little more than a year on an independent joint task force
to review gas ranges and IAQ. There are three working groups. Working group one developed an
inventory of existing standards related to gas ranges/stoves and related items, such as range hood
efficiency. Working group two compiled existing short- and long-term toxicity reference values for CO,
nitrogen dioxide and fine particulate matter. Working group three is developing language that can be
used in voluntary standards to describe how to test gas ranges/stoves in chambers to derive emission
rates for CO, nitrogen dioxide and fine particulate matter. Completion of a voluntary standard test
method will likely take 12-18 months.

New Updates

CPSC staff will publish a request for information in the second quarter of FY 2023 to queue up questions
related to gas range emissions, indoor air concentrations and potential health effects.

Notice of Competition for BPA Call Order Contract

Laboratory in conjunction with the DOE Better Buildings Alliance Space Conditioning Technology
Research Team, https://www.nrel.gov/docs/fv22osti/82174.pdf.

Abstract: This guide provides steps, in conjunction with public health guidance, that small
businesses can take to improve and maintain IAQ. Small businesses often have unique
ownership structures—the building owner and business owner can be different parties—so this
guide addresses both building and business owner action items. Best results are achieved
through a comprehensive approach combining various strategies, including those discussed in
this guide.

The Better Buildings Alliance Space Conditioning Technology Research Team is part of DOE's Better
Buildings Initiative, which is a market transformation program through which partners collaboratively
pursue ambitious energy, waste, water and greenhouse gas reduction goals. More than 900 partners
work with DOE in this effort, including 35 Fortune 100 companies. They share their real-world pathways
for achieving significant savings in their buildings, industrial facilities and multifamily homes. To find out

Register (87 FR 32728, pages 32728-32824) on May 31, 2022.

The simulations considered acrolein and formaldehyde emitted from continuous indoor sources;
acrolein, N02 and PM2.5 from cooking; PM2.5 from dispersed occupant activities; and N02 and
PM2.5 from outdoors using historical data to identify typical levels. The impacts in homes
operating or not operating whole-house mechanical ventilation equipment, kitchen and bath
exhaust fans, and window openings as ventilation approaches were examined.

The analysis found that DOE's proposed standards would lead to substantial improvements in the
protection that manufactured homes provide to occupants against outdoor air pollution. It also
found that concentrations of pollutants from indoor sources may be expected to increase with
DOE's proposed standards if all material emissions and behavioral factors are unchanged. The
analysis also found that increases would be lower in homes using mechanical ventilation that is
required in the HUD code (and would continue to be required, without changes, in the proposed
rule) and that increasing use of mechanical ventilation could lead to lower exposure.

Summary: Researchers conducted a series of wind tunnel experiments and computational fluid
dynamics (CFD) simulations measuring dilution of a horizontally directed exhaust from a test
building. They then compared these measurements to existing models and assessed the models'
validity. Lastly, they gathered dilution criteria for several contaminants of interest and used wind
tunnel and CFD results along with published emission rates to specify a separation distance that
is likely to result in acceptable air quality at neighboring intakes. Results show that mitigation of
chronic health concerns from cooking and smoking in dwelling units, as well as odor concerns
from bathrooms, can likely be achieved with separation distances of 5 feet or less. To prevent
irritation from smoking in neighboring units, a separation distance of 10 feet is recommended.
The researchers did not find that furnace exhaust can be diluted sufficiently with separation
distances that are feasible on multifamily buildings.

Project Contact: Dustin Poppendieck, 301-975-8423, dustin.Dopendieck(S)nist.aov

In spring 2022, NIST hosted the CASA research campaign. A team of 12 external research groups used
environmental and chemical perturbations in the NZERTF to investigate the chemistry of indoor
environments. Chemical transformation induced by ozone, smoke, ammonia, carbon dioxide, insecticide
and VOC additions were investigated. Real-time instruments used in this campaign included a chemical
ionization mass spectrometer, two proton transfer reaction-mass spectrometers, an aerosol mass
spectrometer, a water-soluble gas analyzer and thermal desorption aerosol gas chromatography
instruments. Formaldehyde, NOx, ozone and ultrafine particles were measured with other lab-grade
instruments. A range of consumer-grade sensors were also deployed throughout the NZERTF during the
study. In addition, a variety of surfaces were placed in NZERTF for varying lengths of time to examine the
impact of indoor air chemistry changes on surfaces and the role surfaces play in influencing indoor air
chemistry. These surfaces will be analyzed offsite at collaborators' laboratories. Initial data analysis was
presented in six presentations at the Indoor Air 2022 and American Association for Aerosol Research
40th Annual conferences. Two additional presentations were made at the American Geophysical Union
Fall 2022 Conference. A number of journal articles are also being prepared.

Single-Zone Simulations Using Fate and Transport of Indoor Microbial Aerosols (FaTIMA) for
Reducing Aerosol Exposure in Educational Spaces

Project Contact: Lisa Ng, 301-975-4853, lisa.na(3)nist.aov

FaTIMA was applied to a classroom, portable classroom and assembly room. NIST evaluated the relative
effectiveness of various measures to reduce exposure to infectious aerosols, including wearing masks,
increasing ventilation, increasing filtration, using portable air cleaners and using exhaust fans. Multiple
controls can be implemented in spaces and HVAC systems to reduce exposure as part of a broader risk-
reduction strategy that might be pursued by a building owner or manager. As noted by ASHRAE,
engineering and other controls should be part of a larger, layered risk reduction strategy that includes
hand washing, surface cleaning, social distancing and reduced occupant density. The report can be
downloaded at https://doi.org/10.6028/NIST.TN.2150.

In collaboration with the CDC Foundation and CDC, a set of results from the classroom was incorporated
into a new Interactive School Ventilation Tool on the CDC website:

https://www.cdc.gov/coronavirus/2019-ncov/communitv/schools-childcare/interactive-ventilation-

action, Administrator Michael Regan announced that the Biden administration will resume and
strengthen EPA's commitment to the United Nations Foundation's Clean Cooking Alliance and will work
with the Alliance, foreign governments and partners at every level to reduce emissions from home
cooking and heating that contribute to climate change and affect the health and livelihood of almost
40 percent of the world's population.

During the past year, EPA has continued leading an effort to broaden and strengthen a whole-of-
government approach to addressing this issue. At the 27th meeting of the Council of Parties (COP27), in
Sharm El-Sheikh, Egypt, in November 2022, EPA organized a key event with the Clean Cooking and
Climate Consortium titled "Reducing Emissions from Cooking to Achieve Nationally Determined
Contribution (NDC) Goals." During this event, Administrator Regan discussed the whole-of-government
approach to address this challenge. EPA is working closely with CDC, DOE, the National Institutes of
Health (NIH), the U.S. Department of State and the U.S. Agency for International Development to
implement this climate, health, gender and livelihood initiative.

Advancing Sustainable Household Energy Solutions (ASHES) Initiative at Colorado State University

EPA cooperative partner Colorado State University is collaborating with Berkeley Air Monitoring Group

Working with Countries to Implement Their NDCs

Every country in the world is required under the Paris Climate Agreement to submit a plan to reduce
climate emissions, called their NDCs. Sixty-seven countries have now included references to reducing
emissions from household energy in their NDCs that were submitted at COP26 in Glasgow.

EPA is working with its consortium of partners—called the Clean Cooking & Climate Consortium (4C)—to
support countries in meeting their climate goals by reducing C02, methane, black carbon and other
short-lived climate pollutants. The consortium has been hosting a series of expert consultations to
facilitate more direct interaction with and support for countries in the development of household
energy components in their NDCs, organizing their measurement, reporting and verification (MRV)
activities; financing opportunities; and best practices for scaling clean cooking programs to meet their
national climate goals. This support is facilitating progress in two groups of countries: large group
consultations for any interested countries and stakeholders, and small group consultations where 4C
offers one-on-one support to three countries leading in this sector—Rwanda, Uganda and Ghana.

NIH and other U.S. government agencies helped fund Forum activities and organize a "State of the
Evidence" workshop to showcase the advances made in the clean cooking evidence base. With partners
from the 4C, EPA also helped organize a Monitoring Technology Side Event and an in-person expert
consultation with stakeholders from the Ghanaian government to discuss the household energy climate
emission reduction targets in Ghana's NDC. EPA's participation in these events will help mobilize the
necessary funding, partnerships and policies to achieve clean cooking for all and accelerate progress
toward global climate and development goals.

Radon

National Radon Action Plan (NRAP)

IED continues to support the growing national network of federal agencies, private sector entities,
nongovernmental organizations (NGOs) and states to prevent lung cancer deaths through the NRAP. The
NRAP presents a long-range strategy for eliminating avoidable radon-induced lung cancer in the United
States. On July 20, 2022, the NRAP Leadership Council met to discuss the results from a questionnaire
for states and tribes, the development of a protocol and plan for building a radon resource library, and
the strategic direction for NRAP strategies in FY 2023.

The NRAP Leadership Council invites leaders who are serious about saving lives; building in health
protection where we live, work and learn; eliminating preventable disease; and realizing a high return
on investment in a healthier future to join the NRAP Leadership Council.

State and Tribal Indoor Radon Grants (SIRG)

EPA continues to support programs aimed at risk reduction through the SIRG program. Funding for state
and tribal radon grants in FY 2022 was appropriated at approximately $8,295 million. This is an increase
of $500,000 from the previous year. EPA is currently operating in FY 2023 under a continuing resolution
until at least mid-December and does not yet have a final SIRG program budget for FY 2023.

SIRG Performance Partnership Grant (PPG) Class Exception

In fall 2022, EPA's Office of Grants and Debarment approved a class exception to include the SIRG public
list requirements for states and tribes in all PPGs with SIRG funding. EPA's Office of Air and Radiation
(OAR) believes the public list requirement is necessary for public health protection and should be
applied to SIRG funding included as part of a PPG.

•	The requirement for SIRG recipients to "maintain and make available to the public, a list of firms
and individuals in the State that have received a passing rating under the EPA proficiency rating
program" will be applied consistently for all state and tribal radon grants, including PPGs.

•	This class exception applies to all new and existing PPGs that include SIRG program grants and
will be in place until such time EPA can revise the PPG award regulatory text.

Building Codes

EPA continues to collaborate with industry and states to actively engage in efforts to promote adoption
of radon-resistant new construction practices through international, national, state and local building
codes. These efforts are mandated by the Indoor Radon Abatement Act and are also a key component of
the National Radon Action Plan.

The most recent code change proposal to remove the EPA radon zone map as a reference document for
Appendix F in the International Residential Code was disapproved. EPA wanted to remove the reference
to encourage testing and mitigation everywhere regardless of zone. Some of the committee members
felt that by taking the EPA map of radon zones out of the code, no guidance is left for the local building
officials to make determinations of how close they are to higher-prone areas. EPA is awaiting the results
of the final public comment hearing and the corresponding online voting that took place in Louisville,
Kentucky, from September 11 to 14, 2022.

Radon Credentialina

EPA's work on radon credentialing is part of the Agency's responsibility to promote and support the
availability of quality radon services to the public. Professionals who provide radon testing and
mitigation services play a key role in public health protection efforts. Because of the substantial risk
resulting from exposure to radon, it is critical for radon service providers to possess the necessary skills
to provide quality services and ensure consumer protection. Over the last several years, EPA has been
working, through consultation with states, the public and industry—and in response to congressional
direction—to develop a contemporary framework to guide the credentialing of radon service providers
going forward. EPA remains committed to facilitating access to a qualified workforce through a national
nonregulatory framework that will help establish a quality standard for state-run and independent
programs that credential radon service providers. The Agency plans to soon post an updated proposal
online that reflects stakeholder feedback and hold an information session on the proposal. For more
information about EPA's proposal, visit the EPA radon website at EPA's Draft Criteria for Radon
Credentialing Organizations, where the most up-to-date information will be posted.

EPA's Radon Reference and Intercomoarison Program (ERRIP)

There are annual requirements for secondary radon chambers to be certified to perform radon
measurement and calibration services for the radon industry participating in the National Radon Safety
Board (NRSB), the American Association of Radon Scientists and Technologist's National Radon
Proficiency Program (AARST-NRPP) and state radon programs. The first steps in these certifications are
to participate in ERRIP, managed and operated by the EPA Office of Radiation and Indoor Air's National
Analytical Radiation Environmental Laboratory (NAREL), located in Montgomery, Alabama. NAREL works
with these secondary radon chambers by providing the only U.S. radon reference that is NIST traceable.
There are currently three industry-certified secondary radon chambers for use by the U.S. radon
community. These radon chambers are as follows: Bowser-Morner, Inc., Dayton, Ohio; TCS Industries,
Inc., Harrisburg, Pennsylvania; and KSU Radon Chamber, Manhattan, Kansas.

In June and July 2022, NAREL completed all three commercial radon chamber intercomparisons. The
ERRIP provided the intercomparison radon reference certificates to NRSB and AARST-NRPP for use in
their certification program. The commercial radon chambers will again participate in next year's radon
intercomparison with the ERRIP.

Asthma

Federal Collaboration on Asthma Disparities

EPA staff continue to participate in the monthly Asthma Disparities Subcommittee of the President's
Task Force (PTF) on Environmental Health and Safety Risks to Children. The task force includes
17 federal agencies and is the focal point for federal government agencies to coordinate for the
betterment of children's environmental health. The monthly meetings feature reporting from the PTF
supporting subcommittees that address three priority areas: (1) climate, emergencies and disasters;
(2) asthma disparities; and (3) lead exposures.

EPA staff also participate in the monthly Asthma Disparities Workgroup (ADWG) Leadership Meetings.
The ADWG is an extension of the Federal Asthma Disparities Action Plan and is co-chaired by EPA, the
U.S. Department of Health and Human Services (HHS), and the U.S. Department of Housing and Urban
Development (HUD). The goal of the ADWG is to help minimize the inequities in comprehensive asthma
care. During the meetings, members discuss strategies to advance the three major priority areas of the
Asthma Disparities Subcommittee, which are focused on expanding sustainable financing for in-home
asthma interventions, closing research gaps, and creating equitable expectations for asthma outcomes
for all patients and caregivers.

On October 31, 2022, EPA, in collaboration with CDC, HUD and NIH, hosted the ADWG Full
Subcommittee meeting. The ADWG Full Subcommittee is composed of more than 60 federal
stakeholders committed to coordinating activities and leveraging resources to address nationwide
disparities in asthma health outcomes. Discussion topics for this meeting included progress of the
Centers for Medicare & Medicaid Services Asthma Control Affinity group program; review of EPA's
definition of indoor environmental determinants of health and how these terms contribute to the
broader consideration of the social determinants of health; HUD's smoke-free housing policy and
impacts on children with asthma and disparities and future evaluation plans; and CDC's effects of
climate change on respiratory health, including asthma disparities and its Climate and Health Program.

Allergy and Asthma Network Summit

On November 11, 2002, EPA staff attended the 2022 USAsthma Summit hosted by the Allergy and
Asthma Network. The USAsthma Summit brings together asthma coalitions, state asthma programs,
doctors, school nurses, community health workers, patients, advocates and other key stakeholders
involved in asthma care. During the daylong summit, attendees discussed asthma issues, advanced
guidelines-based care, and shared best practices and lessons learned from asthma programs. EPA's 2022
winner of the National Environmental Leadership Award in Asthma Management, the Utah Department
of Health, shared its award-winning program strategies with participants.

Comprehensive IAQ Interventions in Homes

Indoor airPLUS: New Homes

lED's Indoor airPLUS program is a voluntary partnership and labeling program that helps new home
builders address customer health concerns through construction practices and product specifications
that minimize exposure to airborne pollutants and contaminants. Indoor airPLUS continues to see
sustained growth, with 30 to 50 new partner applications per month over the last quarter. In the second
quarter of calendar year 2022, EPA recorded more than 4,300 Indoor airPLUS-labeled homes—the
highest quarter yet—and by the end of the next reporting period, EPA anticipates a total of 50,000
labeled homes and apartments in the marketplace.

The Indoor airPLUS team has been working on significant changes to the overall program model and
certification scheme in developing version 2, which EPA has been discussing with stakeholders at events
and conferences, such as the recent North American Passive House Conference and the 2022 EEBA
Summit in late September 2022. EPA will release a revised draft of the newly proposed version 2
program model (including a tiered certification system) and specifications for public comment in the
months ahead.

Indoor Air Quality. Healthy Green Cleaning and Preventive Maintenance in Schools

As a result of the COVID-19 pandemic, EPA's Schools Program is focused on the increased interest in
healthy indoor environments in schools, increased urgency to respond to IAQ issues in schools, and
leveraging key partnerships to expand our network of stakeholders. EPA recently participated in several
key events and webinars on IAQ in schools.

On July 8, 2022, EPA participated on a webinar titled "Benefits of Improving Air Quality and Ventilation
in Schools." EPA joined officials from U.S. Department of Education, the White House COVID-19
Coordinator, and experts from CDC to deliver a webinar on the importance of improving air quality in
schools and issue a call to action for schools to use during the summer months to assess school needs
and make improvements. Speakers also addressed the health and academic benefits of improving air
quality.

On July 26, 2022, EPA participated in the U.S. Department of Education's ceremony to recognize the
2022 Green Ribbon Schools Award winners. EPA officials spoke about the importance of IAQ to student
health and learning and highlighted the successful approaches schools are using to improve IAQ during
energy efficiency upgrades. The Green Ribbon program recognizes schools, school districts and post-
secondary institutions for efforts to improve sustainability, protect health and advance environmental
education.

On August 16, 2022, the Biden-Harris administration released an Indoor Air Resource for Back-to-
School—2022 Back-to-School Fact Sheet. The Back-to-School Fact Sheet lays out key supports and
guidance for protecting students, teachers and school communities during the school year, and for
managing and mitigating the risks of COVID-19 spread. This guidance spotlights federal resources,
including some important EPA resources, available for three specific strategies:
