NR 665.1101 in the facility's operating record no later than 60 days after the date of initial operation of the unit. After August 1, 2006, PE certification will be required prior to operation of the unit. The owner or operator shall maintain any of the following records at the facility:
a. A written description of procedures to ensure that each waste volume remains in the unit for no more than 90 days, a written description of the waste generation and management practices for the facility showing that they are consistent with respecting the 90 day limit and documentation that the procedures are complied with.
b. Documentation that the unit is emptied at least once every 90 days. In addition, the generator is exempt from all of the requirements in subchs. G (closure and long-term care) and H (financial requirements) of ch. NR 665, except for ss. NR 665.0111 and 665.0114.
(b) The date upon which each period of accumulation begins is clearly marked and visible for inspection on each container.
(c) While being accumulated on-site, each container and tank is labeled or marked clearly with the words, "Haz-ardous Waste".
(d) The generator complies with the requirements for owners or operators in subch. C (preparedness and preven-tion) and subch. D (contingency plan and emergency procedures) of ch. NR 665 and ss. NR 665.0016 and 668.07 (1) (e).
(2) STORAGE FACILITY LICENSING AND ACCUMULATION TIME EXTENSION. A generator who accumulates hazardous waste for more than 90 days is an operator of a storage facility and is subject to the requirements of chs. NR 664 and 665 and the license requirements of ch. NR 670 unless the generator has been granted an extension to the 90-day period. The department may grant an extension if hazardous wastes must remain on-site for longer than 90 days due to unforeseen, temporary and uncontrollable circumstances. An extension of up to 30 days may be granted at the dis-cretion of the department on a case-by-case basis.
(3) SATELLITE ACCUMULATION. (a) A generator may accumulate as much as 55 gallons of hazardous waste or one quart of acutely hazardous waste listed in s. NR 661.33 (5) in containers at or near any point of generation where wastes initially accumulate, which is under the control of the operator of the process generating the waste, without an operating license or interim license and without complying with sub. (1) provided the generator does all of the follow-ing:
1. Complies with ss. NR 665.0171, 665.0172 and 665.0173 (1).
2. Marks the containers either with the words "Hazardous Waste" or with other words that identify the contents of the containers.
(b) A generator who accumulates either hazardous waste or acutely hazardous waste listed in s. NR 661.33 (5) in excess of the amounts listed in par. (a) at or near any point of generation shall, with respect to that amount of excess waste, comply within 3 days with sub. (1) or other applicable provisions of chs. NR 660 to 673. During the 3-day period the generator shall continue to comply with par. (a) 1. and 2. The generator shall mark the container holding the excess accumulation of hazardous waste with the date the excess amount began accumulating.
Note: Special accumulation requirements for small quantity generators are in s. NR 662.192.
(7) F006WASTEWATER TREATMENT SLUDGES -- 180-DAY ACCUMULATION TIME.

(a) The generator has implemented pollution prevention practices that reduce the amount of any hazardous sub-stances, pollutants or contaminants entering F006 or otherwise released to the environment prior to its recycling.
(b) The F006 waste is legitimately recycled through metals recovery.
(c) No more than 20,000 kilograms (44,100 pounds) of F006 waste is accumulated on-site at any one time.
