My firm is replacing windows on the second floor of a 90-year-old home.  The windows are built into a bay that projects out from a steeply pitched slate roof.  When setting up exterior containment for this job, does the RRP Rule require me to install plastic on the roof under the windows? 

Answer: No. The RRP Rule does not require you to install plastic sheeting on the roof. You must cover the ground with plastic sheeting or other disposable impermeable material in accordance with the containment requirements at 40 CFR 745.85(a)(2).
