requirements of 310 CMR 7.26(10) through (16).
(b) The provisions of 310 CMR 7.26(10)
through (16) apply to the owner or operator of a dry cleaning facility that
has:1. Only dry-to-dry machine(s) and has
perchloroethylene consumption equal to or less than 2,100 gallons per 12-month
rolling period as determined in accordance with 310 CMR 7.26(10)(c)
or
2. Only a transfer machine
system(s) or both dry-to-dry machine(s) and transfer machine system(s) and has
perchloroethylene consumption equal to or less than 1,800 gallons per 12-month
rolling period as determined in accordance with 310 CMR 7.26(10)(c).
(c) When calculating the
perchloroethylene consumption for each 12-month rolling period for the purpose
of determining applicability under 310 CMR 7.26(10)(a), the owner or operator
shall sum on the first day of every month the volume of all perchloroethylene
purchases made in each of the previous 12 months, as recorded in the log
described in 310 CMR 7.26(15)(d)1.
(d) Notwithstanding the forgoing, 310 CMR
7.26 does not apply to dry-to-dry perchloroethylene dry cleaning facilities
co-located with a residence, installed between December 21, 2005 through July
13, 2006. N.B. These dry-to-dry facilities are subject to the
