The first section of this bill establishes its short title, allowing it to be officially referred to as the “Federal Lands Amplified Security for the Homeland Act” or simply the “FLASH Act”.

The document outlines the table of contents for a legislative act aimed at enhancing border security and addressing environmental issues on federal lands. It includes various sections and titles covering border security measures, environmental protection actions related to trash and contaminants, and initiatives to prevent environmental damage from wildfires near the southern border, along with provisions for protecting communities from immigration-related issues.

The section defines several key terms used in the bill, such as "appropriate congressional committees," which are specific groups in the House and Senate, and "border state," which is a state next to the southern border. It also explains "covered Federal lands" as U.S.-owned lands near the southern border, managed by certain agencies, excluding lands held for Indian Tribes. It defines "operational control" as referenced in a past law and identifies who the "Secretary concerned" is based on land jurisdiction. Finally, it defines the "southern border" as the border between the United States and Mexico.

The savings clause clarifies that the Act does not give new powers to limit legal activities like grazing, hunting, and recreation on federal lands, affect state or private lands, or alter agreements with Indian Tribes. It also ensures that the Act does not interfere with border security measures conducted by the Department of Homeland Security or the Department of Defense.

The section explains that to improve border security, the government will build and maintain roads near the southern border, following certain guidelines to allow for better access and control by authorities. Additionally, it outlines plans to incorporate technology like fencing and surveillance, and dictates adherence to environmental regulations throughout the process.

U.S. Customs and Border Protection is allowed to perform certain activities within wilderness areas to secure the international land borders of the United States. These activities include using vehicles, aircraft, and technology, conducting patrols, and building roads, while aiming to protect the natural character of the wilderness areas as much as possible.

The section outlines that a Border State does not need special permission to place temporary structures on federal land along the U.S. southern border if they notify the Secretary at least 45 days in advance. However, these structures can only stay for up to one year unless the Secretary, in consultation with the Commissioner of U.S. Customs and Border Protection, approves an extension in 90-day increments if operational control is not yet achieved.

The section prohibits the Secretary of the Interior and the Secretary of Agriculture from preventing U.S. Customs and Border Protection from performing activities like search and rescue operations and preventing illegal entries, including those by terrorists and the smuggling of drugs, within 100 miles of the southern border on certain federal lands.

The section requires the Secretary involved to make a cooperative agreement with the Secretary of Homeland Security. This agreement is to support a previous understanding about working together on security and counterterrorism efforts on U.S. federal lands near the country's borders.

In this section, two main definitions are provided: "applicable fire and sanitation regulations," which refers to specific rules from the Code of Federal Regulations about maintaining safety and cleanliness on certain federal lands, and "waste," which describes any unwanted materials left by humans without permission or not placed in a proper waste bin.

The bill section requires the Secretary, in coordination with the Secretary of Homeland Security, to create and implement policies within 90 days to reduce environmental harm caused by undocumented immigrants crossing the southern border or camping illegally on Federal lands. The policies should focus on reducing trash, protecting sensitive resources, and preserving wildlife habitats on these lands.

The bill section requires the Secretary to report annually to Congress about trash collected on certain lands, including federal lands and those used by individuals without legal immigration status. The report must detail the amount and cost of waste collection, suggest ways to reduce environmental harm, and include data from various agencies and organizations. Additionally, it should protect the privacy of those providing information and be submitted within a specific timeframe after the fiscal year ends.

In Section 204, the bill outlines penalties for immigrants without legal status who engage in forbidden activities related to fire and sanitation on federal lands. It mandates that within a year, penalties and fines be increased to either double their current levels or to the maximum allowed without exceeding one year in prison or $250,000 in fines, and requires regular reporting on the fines collected.

The section establishes initiatives led by the Secretaries of Agriculture and Interior to manage environmental cleanup from illegal cannabis farming on Federal lands. It provides definitions, outlines goals and responsibilities, and discusses funding and collaboration with other entities to effectively address contamination and restore affected lands, supported by specific budget resources and legal frameworks.

The section describes criminal penalties for private applicators who knowingly break the rules of the Federal Insecticide, Fungicide, and Rodenticide Act. If they violate the Act, they can be fined up to $1,000 or face up to 30 days in jail. If they do this while committing a federal crime, they could be sentenced to up to 10 years in prison.

The amendment to the Act of June 4, 1897, makes it a serious crime to illegally grow cannabis on public lands using pesticides that are not approved by federal law, punishable by a fine of up to $250,000 or up to 20 years in prison, or both.

Anyone who illegally grows cannabis on federal land and violates the Federal Insecticide, Fungicide, and Rodenticide Act could face a fine of up to $250,000 or up to 20 years in prison, or both, in addition to other penalties. "Federal land" refers to land managed by the Bureau of Indian Affairs, Bureau of Land Management, National Park Service, or the United States Fish and Wildlife Service, except land held in trust for an Indian Tribe.

The Southern Border Fuels Management Initiative is a program established by the Secretary of the Interior to manage vegetation along the southern border to prevent wildfires and enhance border safety. It involves reducing hazardous fuels, dealing with invasive species, and creating fuel breaks, with authorized funding of $3,660,000 annually until the program ends 7 years after its start.

The section mandates the creation of policies to reduce wildland fires and environmental damage on federal lands caused by illegal immigration. It requires a report to Congress within a year on these issues and a follow-up update on previous reports regarding wildland fire management.

The section defines key terms used in the context of the bill. It specifies that "Federal land management agencies" include the National Park Service, the Bureau of Land Management, the United States Fish and Wildlife Service, and the Forest Service. It also explains that "housing" refers to camps for sheltering certain aliens, and "specified alien" refers to an alien who hasn't been formally admitted according to immigration law.

The bill prohibits the use of federal funds to provide housing to certain non-citizens on federal land. Additionally, it revokes a specific lease agreement concerning land in the Gateway National Recreation Area with the City of New York and prevents any similar future agreements.

The Secretary of the Interior and the Secretary of Agriculture are required to submit an annual report to congressional committees. This report must detail the number of non-citizens housed on federal land and the countries they originate from.
