Pollution prevention laws and policies
The United States Environmental Protection Agency (EPA) has outlined several laws and policies to prevent pollution and reduce waste. The EPA defines "source reduction" as:
> [Any] practice which: Reduces the amount of any hazardous substance, pollutant, or contaminant entering any waste stream or otherwise released into the environment (including fugitive emissions); prior to recycling, treatment or disposal; and · Reduces the hazards to public health and the environment associated with the release of such substances, pollutants or contaminants.
The EPA encourages cooperation between federal departments, states, and local governments to prevent and control air pollution. The EPA also provides grants to air pollution prevention and control agencies. Furthermore, the EPA may establish record-keeping, inspections, and monitoring for facilities that emit pollutants.
The EPA also has laws and policies in place to address the treatment and storage of hazardous wastes. The EPA can inspect facilities to determine if a waste reduction program is in place and can provide financial assistance to agencies researching waste management and minimization. The EPA also works with federal, state, and local agencies and industries to develop programs to prevent, reduce, or eliminate pollution in navigable, ground, surface, and underground waters.
In addition to the EPA, the International Maritime Organization (IMO), a United Nations agency, has developed the MARPOL convention to address marine pollution from ships. MARPOL includes regulations aimed at preventing and minimizing pollution from ships, both accidental and from routine operations. For example, the discharge of sewage into the sea is prohibited unless the ship has an approved sewage treatment plant or is discharging treated sewage at a distance of more than three nautical miles from the nearest land. MARPOL also includes requirements for the prevention of air pollution from ships, such as limits on nitrogen oxide (NOx) emissions and the use of fuel with lower sulfur content.

Source reduction
The Pollution Prevention Act of 1990 (PPA) mandates that facilities that report to the Toxics Release Inventory (TRI) Program include information on any newly implemented P2 activities. The TRI helps identify effective P2 practices and highlights pollution prevention successes.
In the energy sector, pollution prevention can reduce environmental damage from fuel extraction, processing, transport, and combustion. This can be achieved through the adoption of less environmentally harmful pesticides or the cultivation of crop strains with natural resistance to pests.
In the industrial sector, examples of P2 practices include modifying production processes to produce less waste, using non-toxic or less toxic chemicals, implementing water and energy conservation practices, and reusing materials.
- Initial Environmental Design: Incorporating environmental considerations into the initial process or facility design to limit or prevent pollution or waste generation.
- Process Efficiency Improvements: Modifying processes or facilities to reduce the requirements for hazardous substances, pollutants, or contaminants.
- Material Substitution: Using non-hazardous or less hazardous materials to reduce the toxicity of the resulting waste stream.
- Green Purchasing: Using sustainable practices to acquire bio-based, environmentally preferable, energy-efficient, water-efficient, and recycled-content products.

Cooperation between federal departments, states, and local governments
Encouraging Collaboration: Section 7402 of the US EPA legislation encourages cooperation among federal departments, states, and local governments to work together towards the prevention and control of air pollution. This collaborative effort is vital to ensure a unified approach and consistent implementation of pollution control measures.
EPA's Role: The US Environmental Protection Agency (EPA) plays a central role in facilitating coordination among various agencies involved in air pollution prevention and control. The EPA is mandated to establish a national research and development program for this purpose, as outlined in Section 7403. They also have the authority to provide grants to air pollution prevention and control agencies, as mentioned in Section 7405.
Information Sharing and Standardization: Federal departments, states, and local governments can ensure compliance by sharing information and standardizing procedures. For example, the EPA and the US Coast Guard (USCG) jointly enforce the provisions of MARPOL Annex VI and the Act to Prevent Pollution from Ships (APPS). They conduct inspections, investigations, and take enforcement actions in case of violations. This includes oversight of marine fueling facilities, onboard compliance inspections, and record reviews. Standardization of procedures and record-keeping helps ensure that pollution prevention requirements are met.
Financial Assistance: The EPA provides financial assistance to federal, state, and local agencies involved in researching, investigating, or providing solutions in the areas of waste management and pollution minimization. As per Section 2, grants are appropriated to states to assist in the development of Hazardous Waste Programs. This financial support helps ensure that these agencies have the necessary resources to implement effective pollution prevention measures.
Water Pollution Prevention: In addition to air pollution, cooperation is also crucial in addressing water pollution. The EPA is mandated to work with federal, state, and local agencies, as well as industries, to develop programs for preventing, reducing, or eliminating the pollution of navigable and ground waters. This includes improving the sanitary condition of surface and underground waters, as outlined in Section 1252. Federal, state, and local governments can work together to implement and enforce regulations, such as those outlined in the MARPOL Convention, to minimize water pollution from ships.

EPA inspections and enforcement
Inspectors are encouraged to conduct research on the property and the remodeler before an inspection. This research includes the age and use of the property, whether it receives federal assistance, and any history of elevated blood lead levels among occupants. Additionally, inspectors investigate whether the remodeler has been subject to previous enforcement actions and review relevant information about the remodeler's firm. During the inspection, inspectors break down each provision of the rule and look for evidence of non-compliance, such as improper duct coverage during a worksite inspection.
The EPA also conducts record reviews, where information is reviewed at government agency offices to determine compliance. These reviews may be combined with on-site inspections and can include discharge monitoring reports and permit certifications. Information requests are another tool used by the EPA, where written requests are made to regulated entities for information about a site, facility, or activity.
In the case of marine pollution, the EPA works jointly with the US Coast Guard to enforce the MARPOL Annex VI and the Act to Prevent Pollution from Ships (APPS). This includes inspections, investigations, and enforcement actions for violations, such as overseeing marine fueling facilities and conducting on-board compliance inspections.
The EPA also provides incentives for self-policing through the EPA Audit Policy, encouraging regulated entities to voluntarily discover, disclose, and correct violations, making formal investigations and enforcement actions unnecessary.

International conventions and regulations, such as MARPOL
The International Convention for the Prevention of Pollution from Ships, or MARPOL, is the primary international treaty addressing marine pollution caused by ships. The convention was established in 1973 by the International Maritime Organization (IMO), a United Nations agency focused on maritime safety and security, as well as the prevention of marine pollution from ships.
MARPOL has been instrumental in significantly reducing pollution from international shipping, and its regulations apply to 99% of the world's merchant fleet. The convention includes six technical annexes that address various aspects of pollution prevention, including:
Annex I:
This annex focuses on the prevention of pollution by oil from both operational measures and accidental discharges. The 1992 amendments made it mandatory for new oil tankers to have double hulls and phased in existing tankers to fit double hulls, with subsequent revisions in 2001 and 2003.
Annex II:
Annex II pertains to the control and prevention of pollution from noxious liquid substances in bulk, whether intentional or accidental. It includes requirements for the reception facilities to which ships dispose of residues and mixtures generated from these substances.
Annex VI:
Annex VI specifically addresses air pollution from ocean-going ships, setting limits on nitrogen oxides (NOx) emissions and mandating the use of fuel with lower sulfur content. These measures protect human health and the environment by reducing ozone-producing pollution, which can cause smog and aggravate respiratory issues like asthma.
Other Annexes:
MARPOL also includes annexes that address sewage and garbage disposal, with a particular emphasis on prohibiting the disposal of plastics into the sea. Additionally, there are annexes that outline requirements for ships operating in polar waters, as well as addressing pollution prevention during cargo oil transfers between tankers at sea (ship-to-ship transfers).
To ensure compliance with MARPOL, the IMO actively pursues a proactive approach to implementation and enforcement by flag and port states, including proactive action plans. The US Environmental Protection Agency (EPA) and the US Coast Guard (USCG) also play a crucial role in enforcing MARPOL Annex VI and the Act to Prevent Pollution from Ships (APPS). This includes inspections, investigations, and enforcement actions for violations.
