§ 423.12 Effluent limitations guidelines representing the degree of effluent reduction attainable by the applica-tion of the best practicable control technology currently available (BPT).

(a) In establishing the limitations set forth in this section, EPA took into ac-count all information it was able to collect, develop and solicit with re-spect to factors (such as age and size of plant, utilization of facilities, raw ma-terials, manufacturing processes, non- water quality environmental impacts, control and treatment technology available, energy requirements and costs) which can affect the industry subcategorization and effluent levels established. It is, however, possible that data which would affect these lim-itations have not been available and, as a result, these limitations should be adjusted for certain plants in this in-dustry. An individual discharger or other interested person may submit evidence to the Regional Adminis-trator (or to the State, if the State has the authority to issue NPDES permits) that factors relating to the equipment or facilities involved, the process ap-plied, or other such factors related to such discharger are fundamentally dif-ferent from the factors considered in the establishment of the guidelines. On the basis of such evidence or other available information, the Regional

Administrator (or the State) will make a written finding that such factors are or are not fundamentally different for that facility compared to those speci-fied in the Development Document. If such fundamentally different factors are found to exist, the Regional Admin-istrator or the State shall establish for the discharger effluent limitations in the NPDES Permit either more or less stringent than the limitations estab-lished herein, to the extent dictated by such fundamentally different factors. Such limitations must be approved by the Administrator of the Environ-mental Protection Agency. The Admin-istrator may approve or disapprove such limitations, specify other limita-tions, or initiate proceedings to revise these regulations. The phrase ‘‘other such factors’’ appearing above may in-clude significant cost differentials. In no event may a discharger’s impact on receiving water quality be considered as a factor under this paragraph.

tion (FAA). Available ADF means 75 percent of

the normalized Type I aircraft deicing

fluid and 10 percent of the normalized

Type IV aircraft deicing fluid, exclud-

ing aircraft deicing fluids used for

defrosting or deicing for safe taxiing. Centralized deicing pad means a facil-

ity on an airfield designed for aircraft

deicing operations, typically con-

structed with a drainage system sepa-

rate from the airport main storm drain

system. COD means Chemical Oxygen De-

mand. Collection requirement means the re-

quirement in § 449.11 for the permittee

to collect available ADF. Defrosting means the removal of frost

contamination from an aircraft when

there has been no active precipitation. Deicing mean procedures and prac-

tices to remove or prevent any accu-

mulation of snow or ice on: (1) An aircraft; or (2) Airfield pavement. Deicing for safe taxiing means the ap-

plication of ADF necessary to remove

snow or ice to prevent damage to a tax-

iing aircraft. FAA Advisory Circular means a guid-

ance document issued by the FAA on

methods, procedures, or facility design.

Heating degree day means the number

of degrees per day the daily average

temperature is below 65 degrees Fahr-

enheit. The daily average temperature

is the mean of the maximum and min-

imum temperature for a 24-hour period.

The annual heating degree day value is

derived by summing the daily heating

degree days over a calendar year pe-

riod.

Normalized Type I or Type IV aircraft deicing fluid means ADF less any water

added by the manufacturer or customer

before ADF application.

Primary Airport means an airport de-

commencing operations, to exceed 10,000 annual departures, must comply with the following requirements upon the date the facility exceeds 10,000 an-nual departures. New source perform-ance standards that apply prior to that

date, new source performance stand-

ards for sources that project they will

not exceed 10,000 annual departures

within five years of commencing oper-

ations, and new performance standards

for airports in Alaska, are beyond the

scope of this regulation and shall be de-

termined by the permit authority on a

site-specific basis.

(1) Collection requirement. The new

source must collect at least 60 percent

of available ADF.

(2) Numerical effluent limitation. The

new source must achieve the perform-

ance standards in Table II for available

ADF collected pursuant to paragraph

(a)(1) of this section. The limitation

must be met at the location where the

effluent leaves the onsite treatment

system utilized for meeting these re-

quirements and before commingling

§ 449.20 Monitoring, reporting and rec-ordkeeping requirements.

(a) Demonstrating compliance with the

ADF collection requirement for dis-

chargers subject to NSPS collection re-

quirements in § 449.11. Except as pro-

vided in 40 CFR 125.30 through 125.32,

an individual permittee shall select a

procedure under either paragraphs

(a)(1), (2), or (3) of this section in its

permit application as the procedure for

the permittee to demonstrate compli-

ance with the applicable collection, re-

porting and recordkeeping require-

ments of this Part. A procedure se-

lected by the permittee under para-

graph (a)(2) of this section may be in-

cluded in the permit only with the Di-

rector’s approval, as described in para-

graph (a)(2) of this section. For general

permits, use of alternative methods for

determining compliance with the ADF

collection requirement for dischargers

subject to NSPS collection require-

ments in this part will be at the discre-

tion of the Director.

(1) The permittee shall maintain

records to demonstrate, and certify an-

nually, that it is operating and main-

taining one or more centralized deicing

pads. This technology shall be operated

and maintained according to the tech-

nical specifications set forth in para-

graphs (a)(1)(i) through (iv) of this sec-

tion. For both individual and general

permits, these technical specifications

shall be expressly set forth as require-

ments in the permit. The permittee’s

demonstration and valid certification

are sufficient to meet the applicable

NSPS collection requirement without

the permittee having to determine the

numeric percentage of available ADF

collected.

(i) Each centralized deicing pad shall

be sized and sited in accordance with

all applicable FAA advisory circulars.

Environmental Protection Agency § 449.20

(ii) Drainage valves associated with

the centralized deicing pad shall be ac-

tivated before deicing activities com-

mence, to collect available ADF.

(iii) The centralized deicing pad and

associated collection equipment shall

be installed and maintained per any ap-

plicable manufacturers’ instructions,

and shall be inspected, at a minimum,

at the beginning of each deicing season

to ensure that the pad and associated

equipment are in working condition.

(iv) All aircraft deicing shall take

place on a centralized deicing pad, with

the exception of defrosting and deicing

for safe taxiing.

(2) Alternative technology or specifica-tions. (i) An individual permit (or a

general permit at the discretion of the

Director) may allow one of the fol-

lowing alternative procedures for dem-

onstrating compliance with its collec-

tion requirement, instead of the proce-

dure in paragraph (a)(1) of this section.

The permittee must submit all infor-

mation and documentation necessary

to support this request. An individual

permittee may request this alternative

procedure in its initial permit applica-

tion or permit renewal application.

During the term of an individual per-

mit, the permittee may also request

this alternative procedure as a permit

modification, subject to the require-

ments and procedures at 40 CFR 122.62

and 40 CFR part 124. If the Director de-

termines, in his or her discretion, that

the requested alternative procedure

will achieve the collection requirement

in the permit, the Director shall ap-

prove the request:

(A) The use of a different ADF collec-

tion technology from the centralized

deicing pad technology specified in

paragraph (a)(1) of this section; or

(B) The use of the same ADF collec-

tion technology, but with different

specifications for operation and/or

maintenance.

(ii) Pollution prevention credit. A per-

mittee may apply for, and obtain, full

or partial credit towards compliance

with the available ADF collection re-

quirement. To obtain credit the per-

mittee must demonstrate to the Direc-

tor’s satisfaction that it employs a pol-

lution prevention technique that re-

duces the volume of, or quantity of,

pollutants in, available ADF. The cred-

it shall be equivalent to the dem-

onstrated reduction, as determined by

the Director.

(iii) The Director shall set forth tech-

nical specifications for proper oper-

ation and maintenance of the chosen

collection technology, as appropriate,

and compliance with these technical

specifications must be required by the

permit. The permit shall also require

the permittee to maintain records suf-

ficient to demonstrate compliance with

these requirements. This demonstra-

tion constitutes compliance by the per-

mittee with the percent capture re-

quirement without the permittee hav-

ing to determine the numeric percent-

age of ADF that it has collected. Be-

fore the Director may approve an alter-

nate technology under this subsection,

the permittee must demonstrate to the

Director’s satisfaction that the alter-

nate technology will achieve the appli-

cable percent capture requirement.

(3) The permittee shall maintain

records, by means deemed acceptable

by the Director, and report at a fre-

quency determined by the Director, on

the volume of ADF sprayed and the

amount of available ADF collected in

order to determine the compliance

with the collection requirement.

(b) Monitoring requirements—(1) COD

limitation. Permittees subject to the

ADF collection and discharge require-

ments specified in § 449.11 must conduct

effluent monitoring to demonstrate

compliance with the COD limitation

for all ADF that is collected. Compli-

ance must be demonstrated at the loca-

tion where the effluent leaves the on-

site treatment system utilized for

meeting these requirements and before

commingling with any non-deicing dis-

charge. Effluent samples must be col-

lected following the protocol in Appen-

dix A to this part.

(2) Ammonia limitation. If a permittee

chooses to comply with the compliance

alternative specified in § 449.10(a) or

§ 449.11(b), the permittee must conduct

effluent monitoring at all locations

where pavement deicing with a product

that contains urea is occurring, prior

to any dilution or commingling with

any non-deicing discharge.

Subpart B [Reserved]

APPENDIX A TO PART 449—SAMPLING

PROTOCOL FOR SOLUBLE COD

This sampling protocol applies only to

samples collected for use in measurement of

COD when demonstrating compliance with

the regulations set forth in this part. Collect

a representative sample of the effluent from

the airport deicing treatment system, based

on the discharge permit requirements (e.g., a

grab sample or a composite sample). Because

only the COD sample is filtered, do not use

in-line filters if collecting a sample with a

compositing device.

A. GRAB SAMPLES

1. Cap the container and shake the grab

sample vigorously to mix it. Remove the

plunger from a 10-milliliter (mL) or larger

Luer-lock plastic syringe equipped with an

Acrodisc Luer-lock filter containing a 1.5-μm

glass fiber filter (Whatman 934–AH, or equiv-

alent), and fill the syringe body with sample. 2. Replace the plunger and filter the sam-

ple into a clean 50-mL screw-cap glass, plas-

tic, or fluoropolymer bottle. Note: If testing is being done in the field,

or with a test kit product (e.g., Hach Method

8000), the filtrate may be collected in the

test kit vial or container. 3. Additional 10-mL volumes of sample may

be filtered and the filtrate added to the same

sample bottle. This additional volume may

be used to repeat sample analyses or to pre-

pare Quality Control (QC) samples, as need-

ed. 4. Unless the filtered sample will be ana-

lyzed within 15 minutes, preserve the filtered

sample with H2SO4 to pH <2. Cap the bottle

and label with the sample number. Place in

a cooler on ice prior to shipping. 5. Once at the analytical laboratory, the

sample must be stored at ≤6 degrees Celsius

and analyzed within 28 days of collection (see

the requirements for COD in Table II at 40

CFR part 136).

6. Analyze the sample using a method ap-

proved for COD in Table IB at 40 CFR part

136.

Note: Because this procedure is specific to

this point source category, it does not ap-

pear by name in 40 CFR part 136.

7. Report the sample results as Soluble

COD in units of milligrams per liter (mg/L).

There is no Chemical Abstracts Service

(CAS) Registry Number for soluble COD.

B. COMPOSITE SAMPLES

1. If the sample will be analyzed in a fixed

laboratory (as opposed to field testing),

transfer at least 50 mL of well-mixed sample

from the compositing device into a clean 50-

mL screw-cap glass, plastic, or

fluoropolymer bottle. Preserve the sample

with H2SO4 to pH <2. Cap the bottle and label

with the sample number. Place in a cooler on

ice prior to shipping.

2. Once at the analytical laboratory, the

sample must be stored at ≤6 degrees Celsius

and analyzed within 28 days of collection (see

the requirements for COD in Table II at 40

CFR part 136).

3. Prior to analysis, remove the sample

from cold storage and allow it to warm to

room temperature. Shake the sample vigor-

ously to mix it.

4. Remove the plunger from a 10-mL or

larger Luer-lock plastic syringe equipped

with an Acrodisc Luer-lock filter containing

a 1.5-μm glass fiber filter (Whatman 934–AH,

or equivalent), and fill the syringe body with

sample.

5. Replace the plunger and filter the sam-

ple into a clean COD vial or other suitable

container.

6. Additional 10-mL volumes of sample may

be filtered and the filtrate added to separate

containers, as needed, to provide samples for

repeat analyses or to prepare QC samples.

7. Analyze the sample using a method ap-

proved for COD in Table 1B at 40 CFR part

136.

Note: Because this procedure is specific to

this point source category, it does not ap-

pear by name in 40 CFR part 136.

8. Report the sample results as Soluble

COD in units of mg/L. There is no CAS Reg-

istry Number for soluble COD.

Wet process phosphoric acid is dehy-drated by application of heat and other processing acids such as vacuum and air stripping. The acid is concentrated up to 70–73% P2 O5 in the defluorination process.

§ 422.51 Specialized definitions. For the purpose of this subpart: (a) Except as provided below, the gen-

eral definitions, abbreviations, and methods of analysis set forth in 40 CFR part 401 shall apply to this subpart.

(b) The term process waste water means any water which, during manu-facturing or processing, comes into di-rect contact with or results from the production or use of any raw material, intermediate product, finished product, by-product, or waste product. The term ‘‘process waste water’’ does not include contaminated non-process waste water, as defined below.

(c) The term contaminated nonprocess waste water shall mean any water in-cluding precipitation runoff, which during manufacturing or processing, comes into incidental contact with any raw material, intermediate product, finished product, by-product or waste product by means of:

(1) Precipitation runoff, (2) acci-dental spills, (3) accidental leaks caused by the failure of process equip-ment and which are repaired or the dis-charge of pollutants therefrom con-tained or terminated within the short-est reasonable time which shall not ex-ceed 24 hours after discovery or when discovery should reasonably have been made, whichever is earliest, and (4) dis-charges from safety showers and re-lated personal safety equipment, and from equipment washings for the pur-pose of safe entry, inspection and maintenance; provided that all reason-able measures have been taken to pre-vent, reduce, eliminate and control to the maximum extent feasible such con-tact and provided further that all rea-sonable measures have been taken that will mitigate the effects of such con-tact once it has occurred.

(d) The term ten-year 24-hour rainfall event shall mean the maximum precipi-tation event with a probable recur-rence interval of once in 10 years as de-fined by the National Weather Service in technical paper no. 40, ‘‘Rainfall

Frequency Atlas of the United States,’’ May 1961, and subsequent amendments or equivalent regional or State rainfall probability information developed therefrom.

(e) The term 25-year 24-hour rainfall event shall mean the maximum precipi-tation event with a probable recur-rence interval of once in 25 years as de-fined by the National Weather Service in technical paper no. 40, ‘‘Rainfall Frequency Atlas of the United States,’’ May 1961, and subsequent amendments or equivalent regional or State rainfall probability information developed therefrom.

regulatory authority after consider-ation of soil, climate, and other char-acteristics of a region or State. This term does not apply to those situations in which an operator is mining on flat or gently rolling terrain, on which an occasional steep slope is encountered and through which the mining oper-ation is to proceed, leaving a plain or predominantly flat area.

(e) The term new source remining oper-ation means a remining operation at a coal mine where mining first com-mences after February 22, 2002 and sub-sequently becomes an abandoned mine.

§ 434.71 Applicability. (a) This subpart applies to pre-exist-

ing discharges that are located within or are hydrologically connected to pol-lution abatement areas of a coal re-mining operation.

(b) A pre-existing discharge that is intercepted by active mining or that is commingled with waste streams from active mining areas for treatment is subject to the provisions of § 434.61 Commingling of waste streams. For the purposes of this subpart, § 434.61 re-quires compliance with applicable BPT, BAT, BCT, and NSPS effluent limitations in subparts C, D, and F of this part. Section 434.61 applies to the commingled waste stream only during the time when the pre-existing dis-charge is intercepted by active mining or is commingled with active mine wastewater for treatment or discharge. After commingling has ceased, the pre- existing discharge is subject to the pro-visions of this part.

(c) In situations where coal remining operations seek reissuance of an exist-ing remining permit with BPJ limita-tions and the regulatory authority de-termines that it is not feasible for a re-

mining operator to re-establish base-line pollutant levels in accordance with the statistical procedures con-tained in Appendix B of this part, pre- existing discharge limitations at exist-ing remining operations shall remain subject to baseline pollutant levels es-tablished during the original permit application.

(d) The effluent limitations in this subpart apply to pre-existing dis-charges until the appropriate SMCRA authority has authorized bond release.

§ 434.72 Effluent limitations attainable by the application of the best prac-ticable control technology currently available (BPT).

(iv) TSS ........................................................................................ During remining and reclamation, may not exceed baseline loadings (as defined by Appendix B of this part).

Prior to bond release, the pre-existing discharge must meet the applicable standards for TSS or SS contained in Subpart E. 1

1 A pre-existing discharge is exempt from meeting standards in Subpart E of this part for TSS and SS when the permitting au-thority determines that Subpart E standards are infeasible or impractical based on the site-specific conditions of soil, climate, to-pography, steep slopes, or other baseline conditions provided that the operator demonstrates that significant reductions of TSS and SS will be achieved through the incorporation of sediment control BMPs into the Pollution Abatement Plan as required by paragraph (a) of this section.

(2) If the permitting authority deter-mines that it is infeasible to collect samples for establishing the baseline pollutant levels pursuant to paragraph (b)(1) of this section, and that remining will result in significant improvement that would not otherwise occur, then the numeric effluent limitations in paragraph (b)(1) of this section do not apply. Pre-existing discharges for which it is infeasible to collect samples for determination of baseline pollutant levels include, but are not limited to, discharges that exist as a diffuse groundwater flow that cannot be as-sessed via sample collection; a base flow to a receiving stream that cannot be monitored separate from the receiv-ing stream; a discharge on a steep or hazardous slope that is inaccessible for sample collection; or, a number of pre- existing discharges so extensive that monitoring of individual discharges is infeasible.

APPENDIX B TO PART 434—BASELINE DE-TERMINATION AND COMPLIANCE MON-ITORING FOR PRE-EXISTING DIS-CHARGES AT REMINING OPERATIONS

I. GENERAL PROCEDURE REQUIREMENTS

a. This appendix presents the procedures to be used for establishing effluent limitations for pre-existing discharges at coal remining operations, in accordance with the require-ments set forth in Subpart G; Coal Re-mining. The requirements specify that pol-lutant loadings of total iron, total man-ganese, total suspended solids, and net acid-ity in pre-existing discharges shall not ex-ceed baseline pollutant loadings. The proce-dures described in this appendix shall be used for determining site-specific, baseline pollut-ant loadings, and for determining whether discharge loadings during coal remining op-erations have exceeded the baseline loading. Both a monthly (single-observation) proce-dure and an annual procedure shall be ap-plied, as described below.

b. In order to sufficiently characterize pol-lutant loadings during baseline determina-tion and during each annual monitoring pe-riod, it is required that at least one sample result be obtained per month for a period of 12 months.

c. Calculations described in this appendix must be applied to pollutant loadings. Each loading value is calculated as the product of a flow measurement and pollutant con-centration taken on the same date at the same discharge sampling point, using stand-ard units of flow and concentration (to be de-termined by the permitting authority). For example, flow may be measured in cubic feet per second, concentration in milligrams per liter, and the pollutant loading could be cal-culated in pounds per year.

d. Accommodating Data Below the Max-imum Daily Limit at subpart C of this part. In the event that a pollutant concentration in the data used to determine baseline is lower than the daily maximum limitation established in subpart C of this part for ac-tive mine wastewater, the statistical proce-dures should not establish a baseline more stringent than the BPT and BAT effluent standards established in subpart C of this part. Therefore, if the total iron concentra-tion in a baseline sample is below 7.0 mg/L, or the total manganese concentration is below 4.0 mg/L, the baseline sample con-centration may be replaced with 7.0 mg/L and 4.0 mg/L, respectively, for the purposes of some of the statistical calculations in this Appendix B. The substituted values should be used for all methods in this Appendix B with the exception of the calculation of the interquartile range (R) in Method 1 for the annual trigger (Step 3), and in Method 2 for the single observation trigger (Step 3). The interquartile range (R) is the difference be-

tween the quartiles M–1 and M1; these values should be calculated using actual loadings (based on measured concentrations) when they are used to calculate R. This should be done in order to account for the full range of variability in the data.

II. PROCEDURE FOR CALCULATING AND APPLY-ING A SINGLE-OBSERVATION (MONTHLY) TRIGGER

Two alternative methods are provided for calculating a single-observation trigger. One method must be selected and applied by the permitting authority for any given remining permit.

A. Method 1 for Calculating a Single Observation Trigger (L)

(1) Count the number of baseline observa-tions taken for the pollutant of interest. Label this number n. In order to sufficiently characterize pollutant loadings during base-line determination and during each annual monitoring period, it is required that at least one sample result be obtained per month for a period of 12 months.

(2) Order all baseline loading observations from lowest to highest. Let the lowest num-ber (minimum) be x(1), the next lowest be x(2), and so forth until the highest number (max-imum) is x(n).

(3) If fewer than 17 baseline observations were obtained, then the single observation trigger (L) will equal the maximum of the baseline observations (x(n)).

(4) If at least 17 baseline observations were obtained, calculate the median (M) of all baseline observations:

Instructions for calculation of a median of n observations:

If n is odd, then M equals x(n/2∂1/2). For example, if there are 17 observations,

then M = X(17/2+1/2) = x(9), the 9th highest ob-servation.

If n is even, then M equals 0.5 * (x(n/2) + x(n/2∂1)).

For example, if there are 18 observations, then M equals 0.5 multiplied by the sum of the 9th and 10th highest observations.

(a) Next, calculate M1 as the median of the subset of observations that range from the calculated M to the maximum x(n); that is, calculate the median of all x larger than or equal to M.

(b) Next, calculate M2 as the median of the subset of observations that range from the calculated M1 to x(n) ; that is, calculate the median of all x larger than or equal to M1.

(c) Next, calculate M3 as the median of the subset of observations that range from the calculated M2 to x(n) ; that is, calculate the median of all x larger than or equal to M2.

(d) Finally, calculate the single observa-tion trigger (L) as the median of the subset of observations that range from the cal-culated M3 to x(n).

Environmental Protection Agency Pt. 434, App. B

NOTE: When subsetting the data for each of steps 3a–3d, the subset should include all ob-servations greater than or equal to the me-dian calculated in the previous step. If the median calculated in the previous step is not an actual observation, it is not included in the new subset of observations. The new me-dian value will then be calculated using the median procedure, based on whether the number of points in the subset is odd or even.

(5) Method for applying the single observa-tion trigger (L) to determine when the base-line level has been exceeded

If two successive monthly monitoring ob-servations both exceed L, immediately begin weekly monitoring for four weeks (four weekly samples).

(a) If three or fewer of the weekly observa-tions exceed L, resume monthly monitoring

(b) If all four weekly observations exceed L, the baseline pollution loading has been ex-ceeded.

B. Method 2 for Calculating a Single Observation Trigger (L)

(1) Follow Method 1 above to obtain M1 (the third quartile, that is, the 75th per-centile).

(2) Calculate M¥1 as the median of the baseline data which are less than or equal to the sample median M.

(3) Calculate interquartile range, R = (M1 ¥ M¥1).

(4) Calculate the single observation trigger L as L = M1 + 3 * R

(5) If two successive monthly monitoring observations both exceed L, immediately begin weekly monitoring for four weeks (four weekly samples).

(a) If three or fewer of the weekly observa-tions exceed L, resume monthly monitoring

(b) If all four weekly observations exceed L, the baseline pollution loading has been ex-ceeded.

III. PROCEDURE FOR CALCULATING AND APPLYING AN ANNUAL TRIGGER

A. Method 1 for Calculating and Applying an Annual Trigger (T)

(1) Calculate M and M1 of the baseline load-ing data as described above under Method 1 for the single observation trigger.

(2) Calculate M¥1 as the median of the baseline data which are less than or equal to the sample median M.

(3) Calculate the interquartile range, R = (M1 ¥ M¥1).

(4) The annual trigger for baseline (Tb) is calculated as:

Tb MR

n= + ∗( . )1815

where n is the number of baseline loading ob-servations. (5) To compare baseline loading data to ob-

servations from the annual monitoring pe-riod, repeat steps 1–3 for the set of moni-toring observations. Label the results of the calculations M′ and R′. Let m be the number of monitoring observations.

(6) The subtle trigger (Tm) of the moni-toring data is calculated as:

Tm MR

m= ′ − ∗ ′( . )1815

(7) If Tm > Tb, the median loading of the monitoring observations has exceeded the baseline loading.

B. Method 2 for Calculating and Applying an Annual Trigger (T)

Method 2 applies the Wilcoxon-Mann-Whit-ney test to determine whether the median loading of the monitoring observations has exceeded the baseline median. No baseline value T is calculated.

(1) Steps for Conducting the Wilcoxon-Mann- Whitney Test

(a) Let n be the number of baseline loading observations taken, and let m be the number of monitoring loading observations taken. In order to sufficiently characterize pollutant loadings during baseline determination and during each annual monitoring period, it is required that at least one sample result be obtained per month for a period of 12 months.

(b) Order the combined baseline and moni-toring observations from smallest to largest.

(c) Assign a rank to each observation based on the assigned order: the smallest observa-tion will have rank 1, the next smallest will have rank 2, and so forth, up to the highest observation, which will have rank n + m.

(1) If two or more observations are tied (have the same value), then the average rank for those observations should be used. For example, suppose the following four values are being ranked: 3, 4, 6, 4 Since 3 is the lowest of the four numbers, it would be assigned a rank of 1. The highest of the four numbers is 6, and would be assigned a rank of 4. The other two numbers are both 4. Rather than assign one a rank of 2 and the other a rank of 3, the average of 2 and 3 (i.e., 2.5) is given to both numbers.

(d) Sum all the assigned ranks of the n baseline observations, and let this sum be Sn.

§ 445.1 General applicability. (a) As defined more specifically in

each subpart and except as provided in paragraphs (b) through (h) of this sec-tion, this part applies to discharges of wastewater from landfill units.

(b) The provisions of this part do not apply to wastewater discharges from land application or land treatment units, surface impoundments, under-ground injection wells, waste piles, salt dome formations, salt bed formations, underground mines or caves as these terms are defined in 40 CFR 257.2 and 260.10.

(c) The provisions of this part do not apply to wastewater generated off-site of a landfill facility, including waste-water generated off-site from washing vehicles or from waste transfer sta-tions.

(d) The provisions of this part do not apply to discharges of contaminated ground water or wastewater from re-covery pumping wells.

(e) This part does not apply to dis-charges of landfill wastewater from landfills operated in conjunction with other industrial or commercial oper-ations when the landfill only receives wastes generated by the industrial or commercial operation directly associ-ated with the landfill.

(f) This part does not apply to dis-charges of landfill wastewater from landfills operated in conjunction with other industrial or commercial oper-ations when the landfill receives wastes generated by the industrial or commercial operation directly associ-ated with the landfill and also receives other wastes provided the other wastes received for disposal are generated by a facility that is subject to the same pro-visions in 40 CFR subchapter N as the industrial or commercial operation or the other wastes received are of similar nature to the wastes generated by the industrial or commercial operation.

(g) This part does not apply to land-fills operated in conjunction with Cen-tralized Waste Treatment (CWT) facili-ties subject to 40 CFR Part 437 so long as the CWT facility commingles the landfill wastewater with other non- landfill wastewater for discharge. A landfill directly associated with a CWT facility is subject to this part if the CWT facility discharges landfill waste-water separately from other CWT wastewater or commingles the waste-water from its landfill only with waste-water from other landfills.

forth in 40 CFR 122.2, 257.2, 258.2, 264.10, 265.10, 401.11, and 403.3 the following definitions apply to this part:

(a) Contaminated ground water means water below the land surface in the zone of saturation which has been con-taminated by activities associated with waste disposal.

(b) Contaminated storm water means storm water which comes in direct con-tact with landfill wastes, the waste handling and treatment areas, or land-fill wastewater as defined in paragraph (f) of this section. Some specific areas of a landfill that may produce contami-nated storm water include (but are not limited to): the open face of an active landfill with exposed waste (no cover added); the areas around wastewater treatment operations; trucks, equip-ment or machinery that has been in di-rect contact with the waste; and waste dumping areas.

(c) Landfill directly associated with an industrial or commercial operation means:

(1) A landfill located on the same site as industrial or commercial operations; and

(2) A landfill not located on the same site as the industrial or commercial operations (off-site), but ‘‘wholly- owned’’ by the industrial or commer-cial facility and primarily dedicated to receiving waste from the related indus-trial or commercial facility.

(d) Facility means all contiguous property owned, operated, leased or under the control of the same person or entity.

(e) Landfill unit means an area of land or an excavation in which wastes are placed for permanent disposal, that is not a land application or land treat-ment unit, surface impoundment, un-derground injection well, waste pile, salt dome formation, a salt bed forma-tion, an underground mine or a cave as these terms are defined in 40 CFR 257.2, 258.2 and 264.10.

Subpart L—General Provisions and Definitions

§ 440.130 Applicability. Abbreviations and methods of anal-

ysis set forth in 40 CFR part 401 shall apply to part 440 except as provided in these general provisions and defini-tions. The general provisions and defi-nitions in this subpart apply to all sub-parts of part 440 unless otherwise noted.

§ 440.131 General provisions. (a) Combined waste streams. In the

event that waste streams from various subparts or segments of subparts in part 440 are combined for treatment and discharge, the quantity and con-centration of each pollutant or pollut-

ant property in the combined discharge that is subject to effluent limitations shall not exceed the quantity and con-centration of each pollutant or pollut-ant property that could have been dis-charged had each waste stream been treated separately. In addition, the dis-charge flow from the combined dis-charge shall not exceed the volume that could have been discharged had each waste stream been treated sepa-rately.

(b) Storm exemption for facilities per-mitted to discharge. If, as a result of pre-cipitation or snowmelt, a source with an allowable discharge under 40 CFR part 440 has an overflow or excess dis-charge of effluent which does not meet the limitations of 40 CFR part 440, the source may qualify for an exemption from such limitations with respect to such discharge if the following condi-tions are met:

(1) The facility is designed, con-structed and maintained to contain the maximum volume of wastewater which would be generated by the facility dur-ing a 24-hour period without an in-crease in volume from precipitation and the maximum volume of waste-water resulting from a 10-year, 24-hour precipitation event or treat the max-imum flow associated with these vol-umes. In computing the maximum vol-ume of wastewater which would result from a 10-year, 24-hour precipitation event, the facility must include the volume which would result from all areas contributing runoff to the indi-vidual treatment facility, i.e., all run-off that is not diverted from the active mining area and runoff which is not di-verted from the mill area.

(2) The facility takes all reasonable steps to maintain treatment of the wastewater and minimize the amount of overflow.

(3) The facility complies with the no-tification requirements of § 122.60 (g) and (h). The storm exemption is de-signed to provide an affirmative de-fense to an enforcement action. There-fore, the operator has the burden of demonstrating to the appropriate au-thority that the above conditions have been met.

(c) Storm exemption for facilities not permitted to discharge. If, as a result of precipitation (rainfall or snowmelt), a

source which is not permitted to dis-charge under 40 CFR part 440, has an overflow or discharge which violates the limitations of 40 CFR part 440, the source may qualify for an exemption from such limitations with respect to such discharge if the following condi-tions are met:

(1) The facility is designed, con-structed, and maintained to contain the maximum volume of wastewater stored and contained by the facility during normal operating conditions without an increase in volume from precipitation and the maximum vol-ume of wastewater resulting from a 10- year, 24-hour precipitation event. In computing the maximum volume of wastewater which would result from a 10-year, 24-hour precipitation event, the facility must include the volume which would result from all areas con-tributing runoff to the individual treatment facility, i.e., all runoff that is not diverted from the area or process subject to zero discharge, and other runoff that is allowed to commingle with the influent to the treatment sys-tem.

(2) The facility takes all reasonable steps to minimize the overflow or ex-cess discharge.

(3) The facility complies with the no-tification requirements of § 122.60(g) and (h). The storm exemption is de-signed to provide an affirmative de-fense to an enforcement action. There-fore, the operator has the burden of demonstrating to the appropriate au-thority that the above conditions have been met.

(d) pH adjustment. (1) Where the appli-cation of neutralization and sedimenta-tion technology to comply with rel-evant metal limitations results in an inability to comply with the pH range of 6 to 9, the permit issuer may allow the pH level in the final effluent to slightly exceed 9.0 so that the copper, lead, zinc, mercury, and cadmium limi-tations will be achieved.

(2) In the case of a discharge into natural receiving waters for which the pH, if unaltered by human activities, is or would be less than 6.0 and approved water quality standards authorize such lower pH, the pH limitations for the discharge may be adjusted downward to the pH water quality criterion for

the receiving waters provided the other effluent limitations for the discharge are met. In no case shall a pH limita-tion below 5.0 be permitted.

(e) Groundwater infiltration provision. In the event a new source subject to a no discharge requirement can dem-onstrate that groundwater infiltration contributes a substantial amount of water to the tailing impoundment or wastewater holding facility, the per-mitting authority may allow the dis-charge of a volume of water equivalent to the amount of groundwater infiltra-tion. This discharge shall be subject to the limitations for mine drainage ap-plicable to the new source subcategory.

§ 440.132 General definitions. (a) ‘‘Active mining area’’ is a place
