42. M10 means those offshore

facilities continuously manned by ten

(10) or more persons.

43. No discharge of free oil means that

waste streams may not be discharged

when they would cause a film or sheen

upon or a discoloration of the surface of

the receiving water or fail the static

sheen test defined in appendix 1 to 40

CFR part 435, subpart A.

44. No discharge of diesel oil in

drilling mud means a determination that

diesel oil is not present based on a

comparison of the gas chromatogram

from an extract of the drilling mud and

drilling rig or platform. GC/MS may also

be used.

45. Oil-based drilling mud means a

drilling mud with fossil-derived

petroleum hydrocarbons as the

solid material, that contains as an

essential ingredient one or more

composed of combinations of

degradable starches are either (a)

synthetically produced or (b) naturally

stage of ice formation when

unconsolidated individual ice crystals

(frazil) form a slush layer at the surface

of the water column.

55. SPP means suspended particulate

phase.

56. Stable ice means ice that is stable

enough to support discharged muds and

cuttings.

57. Static Sheen Test means the

standard test procedure that has been

developed for this industrial

subcategory for the purpose of

demonstrating compliance with the

The methodology for performing the

static sheen test is presented in

Appendix 1 to Subpart A of 40 CFR part

435.

58. Step-out well means a new hole

drilled from a main well to a different

bottom hole location.

59. Test fluid means the discharge

which would occur should

hydrocarbons be located during

exploratory drilling and tested for

formation pressure and content. This

would consist of fluids sent downhole

during testing along with water and

particulate matter from the formation.

60. Toxicity as applied to BAT

toxicity test procedure presented in

Appendix 2 to Subpart A of 40 CFR 435.

61. Unstable or broken ice conditions

means greater than 25 percent ice

coverage within a one (1) mile radius of

the discharge site after spring breakup

or after the start of ice formation in the

fall, but not stable ice.

62. Upset means an exceptional

incident in which there is unintentional

and temporary noncompliance with

technology-based permit effluent

limitations because of factors beyond

the reasonable control of the permittee.

An upset does not include

noncompliance to the extent caused by

operational error, improperly designed

treatment facilities, inadequate

unintentional, non-routine or

unanticipated discharges.

66. Water depth means the depth of

the water between the surface and the

seafloor as measured at mean lower low

water (0.0).

67. 24-hour composite sample means

a flow-proportioned mixture of not less

than 8 discrete aliquots. Each aliquot

shall be a grab sample of not less than

100 ml and shall be collected and stored

Hazardous Waste Management

System: Land Disposal Restrictions

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Notice of proposed approval of

application to extend the approved

Case-by-Case Extension of Land

Disposal Restrictions Effective Date.

SUMMARY: EPA is today proposing

approval of the application submitted

by Great Lakes Chemical Corporation

(Great Lakes), requesting an extension to

the June 30, 1995, extended date of the

RCRA land disposal restrictions (LDR)

treatment standards applicable to

wastewaters with the hazardous wastes

codes K117, K118, K131, K132, and

F039. To be granted such a request, the

applicant must demonstrate, among

other things, that there is insufficient

capacity to manage its waste and has

entered into a binding contractual

commitment to construct or otherwise
27524 Federal Register / Vol. 60, No. 100 / Wednesday, May 24, 1995 / Notices

provide such capacity, but due to

circumstances beyond its control, such

capacity could not reasonably be made

available by the effective date. Great

Lakes adequately met these

requirements and was granted an initial

Case-By-Case Extension for one year

effective June 30, 1994 to June 30, 1995,

with the option to renew this extension

for up to one additional year (see FR

5151–3). Based on the Case-By-Case

extension provisions and request by

Great Lakes to extend the ban date,

Great Lakes will be allowed, upon final

approval to land dispose of its K117,

K118, K131, K132, AND F039 wastes

upon final approval, until September

30, 1995, without being subject to the

land disposal restrictions applicable to

such wastes. Final Approval of this

extension, will only be valid for

injection into Well Nos. 5 and 6.

EFFECTIVE DATE: This approved

extension of the LDR effective date

becomes effective May 11, 1995.

Clean Water Act (CWA) 304(l):

Availability of List of Submissions and

Proposed Approval Decisions

AGENCY: U.S. Environmental Protection

Agency (U.S. EPA).

ACTION: Notice of availability.

SUMMARY: This notice announces the

availability of a list submitted to U.S.

EPA pursuant to Section 304(l)(1)(C) of

the CWA, 33 U.S.C. 1314(l)(1)(C) as well

as U.S. EPA’s proposed approval

decision, and request for public

comment.

DATES: Comments must be submitted to

U.S. EPA on or before June 23, 1995.

ADDRESSES: Copies of these items can be

obtained by writing or calling: Mr.

Howard Pham, U.S. EPA—Region 5,

304(l) Coordinator, U.S. Environmental

Protection Agency-Region 5, Water

Division (Mail Code WQP–16J), 77 West

Jackson Blvd., Chicago, Illinois 60604–

3507, telephone: (312) 353–2310.

Comments on these items should be

sent to Howard Pham, U.S. EPA—

Region 5 at the address given above.

FOR FURTHER INFORMATION CONTACT:

Howard Pham at the address and

telephone number given above.

SUPPLEMENTARY INFORMATION: Section

304(l) of the CWA, 33 U.S.C. 1314(l),

required each State, within 2 years after

February 4, 1987, to submit to the U.S.

EPA, three lists of waters, including a

list of those waters in which the State

does not expect to achieve applicable

water quality standards, after

application of technology-based

controls, due to discharges of toxic

pollutants from point sources (the ‘‘B

List’’ or ‘‘Short List’’). 33 U.S.C.

1314(l)(1)(B). The second, or ‘‘Mini’’ list

consists of waters that are not meeting

the new water quality standards

developed under Section 303(c)(2)(B)

for toxic pollutants because of pollution

from point and nonpoint sources. 33

U.S.C. 1314(l)(1)(A)(i). The third, or

‘‘Long’’ list includes all waters on the

other two lists, plus any waters which,

after the implementation of technologybased controls, are not expected to meet

the water quality goals of the Act. 33

U.S.C. 1314(l)(1)(A)(ii).

For each water segment identified in

these lists, the State was required, by

February 4, 1989, to submit a ‘‘C List’’

specifying point sources discharging

toxic pollutants believed to be

preventing or impairing such water

quality. 33 U.S.C. 1314(l)(1)(C).

For each point source identified on

the State’s C list as discharging toxic

pollutants into a water segment on the

State’s B list, the State was further

required to submit to U.S. EPA, an

individual control strategy (ICS) that the

State determined would serve to reduce

point source discharges of toxic

pollutants to the receiving water to a

degree sufficient to attain water quality

standards in that water within 3 years

after the date of the establishment of the

ICS. 33 U.S.C. 1314(l)(1)(D).

U.S. EPA initially interpreted the

statute to require States to identify on

the C list, only those facilities that

discharge toxic pollutants believed to be

impairing waters listed on the B list. In

Natural Resources Defense Council

(NRDC) v. U.S. EPA, the Ninth Circuit

Court of Appeals remanded that portion

of the regulation and directed U.S. EPA

to amend the regulations to require the

States to identify all point sources

discharging any toxic pollutant that is

believed to be preventing or impairing

water quality of any stream segment

listed on any of the three lists of waters,

and to indicate the amount of the toxic

pollutant discharges by each source. See

NRDC v. U.S. EPA, 915 F.2d 1313,

1323–24 (9th Cir. 1990). U.S. EPA

amended 40 CFR 130.10(d)(3)

accordingly. See 57 FR 33040 (July 24,

1992).

Consistent with U.S. EPA’s amended

regulation, the State of Ohio submitted

on April 20, 1992, to U.S. EPA, for

approval a supplemental facility list

(SFL) as required under Section

304(l)(1)(C). U.S. EPA’s review of Ohio’

304(l) SFL and its procedures used to

develop the list, found the procedures to

be consistent with the requirements of

the amended regulations. Based on the

above findings, U.S. EPA noticed the

availability of Ohio’s SFL, as well as the

Agency’s proposed approval decisions

and request for public comments (see

U.S. EPA’s Notice of Availability and

Proposed Approval Decisions published

at FR 12332, March 24, 1994).
