If there has been a leak or a spill from a tank system or
secondary containment system, or if either system is unfit for use, remove the
system from service immediately and satisfy the following requirements:
(1) Immediately stop the flow of hazardous
waste into the tank system or secondary containment system and inspect the
system to determine the cause of the release.
(2) Remove the waste from the tank system or
secondary containment system.
(a) If the
release was from the tank system, within 24 hours after detecting the leak,
remove as much of the waste as is necessary to prevent further release of
hazardous waste to the environment and to allow inspection and repair of the
tank system to be performed.
(b) If
the material released was to a secondary containment system, remove all
released materials within 24 hours or as quickly as possible to prevent harm to
human health and the environment.
(3) Immediately conduct a visual inspection
of the release and, based upon that inspection:
(a) Prevent further migration of the leak or
spill to soils or surface water.
(b) Remove, and properly dispose of, any
visible contamination of the soil or surface water.
(4) Report any release to the environment,
except as provided in par. (a) to the department within 24 hours of its
detection. If you have reported the release pursuant to ch. NR 706, that report
will satisfy this requirement.
(a) You need
not report on a leak or spill of hazardous waste if it is:
1. Less than or equal to a quantity of one
pound; and
2. Immediately contained
and cleaned up.
(b)
Within 30 days of detection of a release to the environment, submit a report to
the department containing the following information:
1. The likely route of migration of the
release.
2. The characteristics of
the surrounding soil (soil composition, geology, hydrogeology,
climate).
3. The results of any
monitoring or sampling conducted in connection with the release (if available).
If sampling or monitoring data relating to the release are not available within
30 days, submit these data to the department as soon as they become
available.
4. The proximity to down
gradient drinking water, surface water, and populated areas.
5. A description of response actions taken or
planned.
(5)
Either close the system or make necessary repairs.
(a) Unless you satisfy the requirements of
pars. (b) and (c), close the tank system according to s.
NR 667.0201.
(b) If the cause of the release was a spill
that has not damaged the integrity of the system, you may return the system to
service as soon as you remove the released waste and make any necessary
repairs.
(c) If the cause of the
release was a leak from the primary tank system into the secondary the
secondary containment system, you shall repair the system before returning the
tank system to service.
(6) If you have made extensive repairs to a
tank system in accordance with sub. (5) (for example, installation of an
internal liner or repair of a ruptured primary containment or secondary
containment vessel), you may not return the tank system to service unless the
repair is certified by a qualified professional engineer in accordance with s.
NR 670.011(4).
(a) The engineer shall certify that the
repaired system is capable of handling hazardous wastes without release for the
intended life of the system.
(b)
You shall submit this certification to the department within seven days after
returning the tank system to use.
