    (b) Disaster Funding.--Section 251(b)(2)(D) of the Balanced Budget 
and Emergency Deficit Control Act of 1985 (2 U.S.C. 901(b)(2)(D)) is 
amended--
            (1) in clause (i)--
                    (A) in subclause (I), by striking ``and'' and 
                inserting ``plus'';
                    (B) in subclause (II), by striking the period and 
                inserting ``; less''; and
                    (C) by adding the following:

                                authority provided in an appropriation 
                                Act for wildfire suppression operations 
                                pursuant to subparagraph (E) for the 
                                preceding fiscal year.''; and
            (2) by adding at the end the following:
                            ``(v) Beginning in fiscal year 2018 and in 
                        subsequent fiscal years, the calculation of the 
                        `average funding provided for disaster relief 
                        over the previous 10 years' shall include the 
                        additional new budget authority provided in an 
                        appropriation Act for wildfire suppression 
                        operations pursuant to subparagraph (E) for the 
                        preceding fiscal year.''.
    (c) Reporting Requirements.--If the Secretary of the Interior or 
the Secretary of Agriculture determines that supplemental 
appropriations are necessary for a fiscal year for wildfire suppression 
operations, such Secretary shall promptly submit to Congress--
            (1) a request for such supplemental appropriations; and
            (2) a plan detailing the manner in which such Secretary 
        intends to obligate the supplemental appropriations by not 
        later than 30 days after the date on which the amounts are made 
        available.
Wildfire Disaster Funding Act of 2015 This bill amends the Balanced Budget and Emergency Deficit Control Act of 1985 to require specified adjustments to discretionary spending limits in FY2016-FY2025 to accommodate appropriations for wildfire suppression operations in the Wildland Fire Management accounts at the Department of Agriculture (USDA) or the Department of the Interior. If USDA or Interior determines that supplemental appropriations are necessary for wildfire suppression operations, the bill requires the relevant department to submit to Congress a request for the funding and a plan for obligating the funds.  The bill also requires the President's budget to include the average costs for wildfire suppression over the previous 10 years.
