The Minnesota Legislature took up three budget bills Friday as the deadline approaches to pass a two-year budget.

The House considered bills dealing with environmental and natural resource programs as well as state agency operations. The Senate acted on a bill to pay for health, human services and related programs. The three bills will be part of end-of-session budget negotiations among legislators and Gov. Mark Dayton.

Here are some key elements of those bills:

HOUSE ENVIRONMENT AND NATURAL RESOURCES BILL

- Replaces a requirement that boaters complete aquatic invasive species training and post a decal on trailers with a new affirmation of awareness.

- Establishes a new competitive grant program aimed at increasing recycling rates in rural Minnesota communities that have less than 45,000 residents.

- Gives the Legislature veto power over water quality and other environmental rules deemed to have a significant financial impact on permit applicants.

- Shakes up the makeup and duties of the Minnesota Pollution Control Agency citizen's board.

- Includes money for study of health impacts of crumb rubber in synthetic-turf athletic fields.

- Proposes a new, site-specific approach for protecting water quality against sulfate pollution.

HOUSE STATE GOVERNMENT FINANCE BILL

- Caps the state's employee numbers at roughly 36,000.

- Limits salary hikes for the governor's cabinet members - those increases could be no larger than the bumps in Minnesota residents' median incomes or the rate of inflation.

- Cuts the new Metropolitan Council chair's salary in half and removes the governor's authority to appoint council members, requiring them to be elected city or county officials.

- Reduces staff budgets for the House and Senate by 5 percent.

- Eliminates the grand total limits on how much money political candidates can accept from lobbyists and outside political funds.

- Repeals the state's public campaign subsidy program, which is funded through an income tax check-off.

SENATE HEALTH AND HUMAN SERVICES BILL

- Directs $52 million more to child-protection programs to provide more staff to investigate abuse claims and oversight.

- Increases monthly grants to welfare recipients by $100.

- Restructures the MNsure health insurance exchange to move it from an independently governed entity to a state agency.

- Provides additional money for Minnesota sex offender evaluations and appeals of civil confinement decisions.

- Boosts payment increases to nursing home facilities by $25.1 million, or an average of 5 percent per facility, to increase wages and benefits of workers.

- Modifies and adds to the rural health professional loan forgiveness program to cope with dentist, doctor and nurse shortages in remote places.

- Expands programs to assist homeless or sexually exploited youth.

- Supplies $36 million in grants for improvements to mental health treatment.
