Subp. 8.
Satellite accumulation.
Items A to D apply to all generators of hazardous
waste.
A. A generator may, without a

7, accumulate as much as 55
gallons of hazardous waste or one quart of acute hazardous waste listed in part
7045.0135, subpart 1a, items B to
D, per waste stream per each point of generation provided the generator
complies with items B to D.
B. The
generator must:
(1) comply with part
7045.0626, subparts
2 to
4 and
6;
(2) clearly label each container with the

small quantity generator, or with part
7045.0566 if a very small quantity
generator;
(4) provide that outdoor
satellite accumulation areas are protected from unauthorized access and
inadvertent damage from vehicles or equipment; and
(5) provide that containers that hold free
liquids are placed on a containment surface that is impermeable to the waste
stored and, if outside, is curbed.
C. In addition, the generator must:
(1) for a container or containers located
within the immediate working area of the specific process producing the waste,
provide direct control and visual inspection of the satellite accumulation area
by persons directly responsible for the specific process producing the waste;
or
(2) for a container or
containers not located in the immediate working area, inspect the containers
and areas where containers are stored, at least weekly, looking for leaks and
for deterioration caused by corrosion or other factors and keep a written
record of the dates and findings of these inspections.
D. On the date on which the volume limit
prescribed in item A is reached, the generator must:
(1) clearly label the container or containers
with that date (that date is then the accumulation start date);
(2) within three days thereafter, transfer
the entire satellite container's or containers' contents to the hazardous waste
storage area and comply with subparts
1 to
7, as applicable;
and
(3) during the three-day period
for compliance, continue to comply with items B and C.
Subp. 9.
Transportation time
extension.
If waste accumulated under subparts
5 and
6 must be transported 200
miles or more to a facility, the generator may store the waste for an
additional 90 days beyond the established limits. In this event, the generator
must maintain evidence on site that arrangements have been made for the
transport of the waste to the facility and, if requested, show the evidence to
the commissioner. During this time extension a small quantity generator shall
not at any time exceed the 3,000 kilogram accumulation limit established in
subpart
5 and a very small quantity
generator shall not at any time exceed the 1,000 kilogram limit established in
subpart
6.
Subp. 10.
Time extension.
One extension may be granted for up to 30 days by the
commissioner if hazardous waste must remain on site for longer than the maximum
allowable time under subparts
1 to
9, as applicable, due to
unforeseen, temporary, and uncontrollable circumstances. A request for an
extension must be submitted in writing to the commissioner and must
include:
A. the amount and type of
waste to be stored over the maximum allowable number of days;
B. the date the stored waste will exceed the
maximum allowable number of days;
C. the location of the waste needing an
extension;
D. the reason for the
extension request; and
E.
documentation of the generator's effort to ship the waste off site within the
applicable time limit.
Subp.
11.
Accumulation requiring a permit.
A large quantity generator who accumulates hazardous waste
for more than 90 days, or a small quantity generator who accumulates more than
3,000 kilograms of hazardous waste at any time, is an operator of a storage
facility and is subject to the requirements of parts
7045.0450 to
7045.0649 and the agency's
permitting procedures in chapter 7001 unless the generator has been granted a
time extension under subpart
10.
Subp. 12.

designated facility with the understanding that the designated facility can
accept and manage the waste and later receives that shipment back as a rejected
load or residue according to the manifest discrepancy provisions of part
7045.0476 or
7045.0582 may accumulate the
returned waste on-site according to subparts
1 to
7,
9, and
10, depending on the amount
of hazardous waste on-site in that calendar month. Upon receipt of the returned
shipment, the generator must:
