FACTBOX-Miscellaneous provisions in US energy bills

July 29 (Reuters) - The U.S. Congress will consider energy bills in the coming days that would implement offshore drilling reforms in response to the BP (BP.L) (BP.N) oil spill.

Here are some of the less prominent provisions scattered throughout the hundreds of pages of both bills.

SENATE BILL:

* Energy companies that use hydraulic fracturing to remove oil or natural gas trapped in shale rock would have to disclose starting in 2012, or sooner if a state required, the chemicals used in the injected drilling fluid. Some environmental groups are worried hydraulic drilling fluids might contaminate drinking water supplies.

* The fee paid by oil companies into the federal Oil Spill Liability Trust Fund would increase from 8 cents a barrel to 45 cents.

* A state may require any person to provide it or the U.S. Coast Guard with notice 24 hours or more before transferring more than 250 barrels of oil in bulk as cargo to, from, or within a vessel in State waters.

* Gives the presidential commission investigating the BP oil spill subpoena power to compel individuals, including oil company executives, to testify or produce books, records and other documents related to the spill. Subpoenas can't be issued if the U.S. attorney general believes taking certain testimony would interfere with a federal or state criminal investigation of the spill.

* Requires administrator of the BP compensation fund to provide Congress with a report every 90 days listing each claim paid from the fund.

* The Energy Department would have to publish a monthly report on the effect the Obama administration's offshore drilling moratorium is having on oil and gas exploration jobs and its impact on small businesses along the Gulf Coast.

HOUSE BILL:

* Imposes a new conservation fee of $2 on every barrel of oil and 20 cents on every one thousand cubic feet of natural gas drilled on federal leases located both onshore and offshore. The fee would expire at the end of 2021.

* Requires the Interior Department to determine within two years the offshore boundaries of coastal states. This would make sure offshore drilling does not spill over into Florida waters as the state does not allow oil exploration off its shore.

* Gives the Coast Guard 90 days to complete an inventory of all vessels operating in U.S. waters that are capable of responding to a major oil spill. The vessel inventory would be updated every quarter.

* Offshore drilling rigs searching for oil or natural gas in U.S. waters have to be built in the United States, unless the government provides a waiver because no U.S.-built offshore facilities are available or an emergency requires the use of an foreign rig.

* Modifies the purpose of the government's offshore oil and gas leasing plan that is issued every five years so it will no longer just "meet national energy needs," but instead will "balance national energy needs and the protection of the marine and coastal environment and all the resources in that environment."
