1. IDENTIFICATION OF THE INFORMATION COLLECTION
1(a)

Title of the Information Collection

ICR: Turbidity Monitoring Requirements For Construction Sites Regulated By The Effluent
Limitations Guidelines and Standards For The Construction and Development Point Source
Category (40 CFR Part 450) (EPA ICR No. 2336.01).
1(b)

Short Characterization/Abstract

This Information Collection Request (ICR) presents estimates of the burden and costs to
the regulated community associated with implementation of the monitoring requirements of the
Effluent Limitations Guidelines and Standards For The Construction and Development Point
Source Category (40 CFR Part 450). The guidelines require regulated operators to perform
turbidity monitoring through the measurement and recording the levels of effluent nephelometric
turbidity units (NTU)
EPA estimates that total annual burden and costs of the proposed guidelines are 223,800
hours and $11.2 million, affecting approximately 5,595 regulated entities. “Regulated entities”
are defined, for purposes of this ICR, as construction sites larger than 30 acres, with 10 percent
or greater, by mass, of soils less than 2 microns in diameter (down to the graded level of the site),
and with rainfall erosivity factors (R factors) of 50 or higher, as defined by the Revised
Universal Soil Loss Equation (for construction activity located in Alaska or a U.S. territory
where the R factor applicable to the activity has not been calculated, the 30-year average total
annual precipitation of 20 inches or more shall be used in place of the R factor).
This is a new ICR.

Turbidity Monitoring Requirements for Construction Sites

2. NEED FOR AND USE OF THE COLLECTION
2(a)

Need/Authority for the Collection

As mentioned above, EPA established monitoring requirements for construction sites
under authority of Clean Water Act (CWA) Section 308 to demonstrate compliance with effluent
limitations and standards for turbidity promulgated under 40 CFR Part 450. Sediment, created as
a result of construction and development (C&D) activity and measured by turbidity, is the
primary pollutant that causes water quality impairment for streams and rivers. It is also one of
the leading causes of lake and reservoir water quality impairment and wetland degradation. The
sediment entrained in stormwater discharges from construction activity can harm aquatic
ecosystems, increase drinking water treatment costs, and degrade recreational uses of impacted
waters. Sediment can also accumulate in rivers, lakes, and reservoirs, leading to the need for
dredging or other mitigation. Additionally, Section 402(a)(2) of the CWA directs EPA to
prescribe permit conditions to assure compliance with requirements “including conditions on
data and information collection, reporting and such other requirements as [the Administrator]
deems appropriate.”
2(b)

Practical Utility/Users of the Data

The primary users of the data are the owners and operators of construction sites and
NPDES permitting and enforcement authorities. Citizen groups also use this data to
independently assess compliance.
EPA expects that the monitoring reports will be used by NPDES control authorities to
determine compliance with the effluent limitations and standards. EPA, States, and local
authorities also analyze monitoring data when establishing permit conditions and revise permit
requirements based on data from monitoring reports. Furthermore, EPA and States refer to
discharge monitoring reports and monitoring data on pollutants when developing lists of waters
not meeting applicable water quality standards. EPA anticipates that State NPDES permitting
authorities will only need to conduct detailed technical reviews of monitoring reports in the event
the monitoring reports indicate noncompliance with the NPDES permit conditions.
EPA anticipates that permittees will use the monitoring data to track the effectiveness and
progress of reducing pollutant discharges. Collection and reporting of data to permitting
authorities also provides permittees with an incentive to remain in compliance with their
established permit limitations and conditions.
As public information, monitoring data is used by public environmental/citizen groups
for a variety of purposes. Citizen groups review monitoring data to independently assess
discharger compliance. In some instances the data forms the basis for citizen suits that are
authorized under Section 505 of the CWA. In addition, environmental groups, academicians and
others use monitoring data to estimate pollutant loadings to streams, lakes, oceans, and estuaries.

NON-DUPLICATION, CONSULTATIONS, AND OTHER COLLECTION
CRITERIA
3(a)

Non-duplication

EPA has examined all other reporting requirements contained in the Clean Water Act and
40 CFR Parts 122, 123, 124, 125, 430, 501, and 503. The Agency also has consulted the
following sources of information to determine if similar or duplicate information is available
elsewhere:
•

EPA Information Systems Inventory,

•

State permits,

•

Government Information Locator System (GILS), and

•

Toxic Chemical Release Inventory.

Examination of these databases revealed no duplicate collection requirements. EPA has
concluded that there is no other way to obtain the compliance demonstration information
addressed in this ICR.
3(b)

Public Notice Required Prior to ICR Submission

EPA intends to solicit comment on this draft ICR prior to formal submission to OMB. A
notice is being published in the Federal Register indicating this intent. Interested parties have
60 days to submit comments on the ICR to EPA. See 5 CFR 1320.8 (d)(1).
3(c)

Consultations

As mentioned above, EPA solicits public comments on the current draft ICR.
Additionally, EPA will consult with the public, industry, and States on the monitoring
requirements during the rulemaking process.
3(d)

Effects of Less Frequent Data Collection

EPA has established its turbidity monitoring frequency to coincide with effluent
discharges from construction sites. Since this frequency depends on local weather conditions
and sediment basin characteristics, monitoring will be somewhat sporadic. EPA determined that
this minimum required monitoring frequency was necessary because of the degree of the
temporal variability in effluent discharges from construction sites that can and do occur
frequently and at any time. Therefore, EPA was concerned that less frequent monitoring would
not provide the information necessary to ensure compliance with the effluent limitations
guidelines and standards promulgated for this industry.

3

Turbidity Monitoring Requirements for Construction Sites

In establishing the minimum monitoring frequency for turbidity, EPA has struck a
balance between the cost of the monitoring regimen and the need to ensure that sufficient data is
consistently available to permitting authorities. Permitting authorities need to have an adequate
basis to verify compliance with the effluent limitations guidelines and standards, given the
environmental significance of large discharges of sediment, and the generation of which is
variable, as available data clearly demonstrate. This monitoring regimen also ensures sufficient
data is available to the site operator so that it may quickly become aware of noncompliance with
the limits of the rule and remedy it as soon as practicable.
3(e)

General Guidelines

This information collection is consistent with OMB guidelines contained in 5 CFR
1320.5(d)(2).
3(f)

Confidentiality

EPA does not expect that confidential business information (CBI) or trade secrets will be
required from C&D site operators as part of this ICR. Where information submitted in
conjunction with this ICR contains CBI, the respondent may request that this information be
treated as confidential business information. All data so designated will be handled pursuant to
40 CFR Part 2 when EPA is the permitting authority, and pursuant to applicable state rules and
regulations governing CBI when states are the permitting authorities. Pursuant to Section 308(b)
of the Clean Water Act, effluent data may not be treated as confidential.
3(g)

Sensitive Questions

The reporting requirements addressed in this ICR do not include sensitive questions.

THE RESPONDENTS AND THE INFORMATION REQUESTED
4(a)

Respondents and SIC Codes

The respondent universe for this ICR will be approximately 5,595 construction sites.
These construction sites are, as noted above, larger than 30 acres, with 10 percent or greater, by
mass, of soils less than 2 microns in diameter (down to the graded level of the site), and with R
factors of 50 or higher (for construction activity located in Alaska or a U.S. territory where the R
factor applicable to the activity has not been calculated, the 30-year average total annual
precipitation of 20 inches or more shall be used in place of the R factor).
4(b)

Information Requested

The following sections outline the monitoring, reporting, and recordkeeping requirements
for construction sites under 40 CFR 450. Table 4.1 outlines the information requirements for
respondents and the data requirements are listed by regulation number.

40 CFR Citation

Should a permittee choose to collect and analyze more samples than specified in its
permit, the permittee must include all monitoring data in the reports. See 40 CFR
122.41(j)(4)(ii). As indicated in Table 4.1, submission of reports shall be at the frequency
established by the NPDES permit authority, but in no case less than once per year. Also, the
permittee must collect and analyze representative samples and must conduct all monitoring
requirements according to permit specific conditions and/or approved test procedures as set forth
under 40 CFR Parts 136, 430, and 503. See 40 CFR 122.41(j).
A sample of a pre-printed discharge monitoring form may be obtained from the

5

Turbidity Monitoring Requirements for Construction Sites

NPDES/Sewage Sludge Monitoring Reports ICR. Direct dischargers are required to maintain
monitoring records, copies of all reports required by the NPDES permit agreement and records
of all data used to complete the permit application for at least 3 years. See 40 CFR 122.41(j)(2).
Construction site respondent activities include the following:
•

Preparing basic information. All permittees must conduct a variety of basic
activities, including reviewing regulatory and permit requirements, conducting
monitoring; preparing DMRs, and submitting reports to the NPDES permit
authority.

•

Maintaining records. All permittees must keep records of monitoring
information as required by the regulation.

NPDES-authorized States respondent activities include the following:
•

DMR Review

•

Follow-up Activities

•

Reporting and Recordkeeping Requirements

Data review varies from State to State. Generally, the permitting authority routinely
screens data to identify permit violations and conducts a more thorough technical review and
follow-up when violations are detected. Follow-up activities may include informal contact with
the permittee (by telephone or letter) requesting prompt corrective action, technical assistance,
field inspections to further substantiate violations, or a formal enforcement action, such as an
Administrative Order or referral to the EPA regional office and/or the U.S. Attorney (or State's
Attorney General in the case of NPDES-authorized States). Table 4.2 summarizes NPDESauthorized State requirements.

THE INFORMATION COLLECTED--AGENCY ACTIVITIES, COLLECTION
METHODOLOGY, AND INFORMATION MANAGEMENT
5(a)

Agency Activities

Activities undertaken by EPA under this information collection primarily include
oversight of the NPDES programs and, where EPA is the NPDES permitting authority, review of
monitoring data and, where necessary, follow-up actions.
The extent to which EPA reviews data in assessing permit compliance may vary. For
example, EPA may conduct a more extensive review of permittees that are, or have been, in
violation of their permit requirements, than of permittees who have been in full compliance. In
cases of continued noncompliance, EPA may use monitoring report data to identify patterns of
non-compliance and/or to support Agency enforcement efforts. EPA and/or the permitting
authorities may limit its review of data submitted by fully compliant permittees to a simple
determination of continuing compliance. EPA may also review data from minor permittees that
may cause water quality problems (i.e., significant minors). EPA may review data from other
minor permittees less frequently. In most cases, EPA will forward copies of reports to the States.
EPA does not require the unauthorized States to review data, but several States voluntarily
conduct the review and use the results in their own programs.
EPA regions may also review data from major direct discharging permittees while
performing program oversight functions (e.g., during file audits and when compiling statistical
compliance summaries). Reported data is often stored in the Permit Compliance System (PCS)
for reference. EPA and States may use this data to evaluate potential compliance problems,
focus inspection efforts, conduct spot check reviews and determine appropriate enforcement
action. PCS is available for public review at the following location:
http://www.epa.gov/enviro/html/pcs/pcs_overview.html.
5(b)

Collection Methodology and Management

Respondents typically report collected compliance data for all pollutant parameters on
Discharge Monitoring Reports (DMRs). Use of preprinted DMR forms is one method that EPA
has used to improve its collection methodology. EPA has developed policy guidance for the
electronic submission of data (see 61 FR 46683-46694). The electronic submission of DMR data
is voluntary and will be an alternative to the paper submissions. EPA makes use of the PCS
database to store, track and access this information.
5(c)

Small Entity Flexibility

EPA has certified that effluent guidelines for C&D sites, including the monitoring
requirements considered by this ICR, will not have a significant economic impact on a
substantial number of small entities and therefore is not establishing any reporting or
recordkeeping alternatives for small entities. See Section XII.7 of the Preamble.

Turbidity Monitoring Requirements for Construction Sites

5(d)

Collection Schedule

The information collection activities included in this ICR are anticipated to coincide with
existing reporting schedules. The timeframes for submitting compliance assessment information
and associated activities are outlined below:
•

Monitoring, reporting, and recordkeeping are performed on a continual basis;

•

Reports are to be prepared for submission to NPDES permit authorities at a
frequency to be determined by these authorities, but no less than once per year. EPA
expects that such reporting frequencies will be consistent with existing reporting
requirements already applicable to permittees.

ESTIMATING THE BURDEN AND COST OF THE COLLECTION
6(a)

Estimating Respondent Burden

This section describes the methods EPA used to estimate the burden to respondents
associated with the monitoring and reporting requirements reports of 40 CFR Part 450.
The number of sites potentially affected by this ICR is estimated at 5,595 and the number of rain
events that would subsequently require effluent monitoring is estimated at 20. For purposes of
calculating the response burdens of control authorities, EPA estimates that activities at
construction sites persist for nine months out of every year.
(i)

Sampling and Reporting Activities

All construction sites larger than 30 acres, with 10 percent or greater, by mass, of soils
less than 2 microns in diameter (down to the graded level of the site), and with rainfall erosivity
factors (R factors) of 50 or higher, as defined by the Revised Universal Soil Loss Equation (for
construction activity located in Alaska or a U.S. territory where the R factor applicable to the
activity has not been calculated, the 30-year average total annual precipitation of 20 inches or
more shall be used in place of the R factor) will be required to monitor effluent turbidity
following rain events that lead to stormwater discharges from the sites. The Agency assumes the
use of simple turbidimeters and basic automated data loggers and two hours per rain event for
sampling and recordkeeping. The annual permittee burden is, therefore, estimated as follows:
(2 hours/rain event)*(20 rain events/site/year) = 40 hours/site/year
(ii)

NPDES-authorized State Respondent Burden

The burden and associated costs to NPDES-authorized State authorities for reviewing
DMRs, revising NPDES permits, and conducting follow-up actions are estimated at 0.5 hours per
site per month. The annual State respondent burden is, therefore, estimated as follows:
(0.5 hours/site/month)*(9 months construction/year) = 4.5 hours/site/year
A summary of permittee and control authority burden is presented in Table 6.1, below.

6(b)

Estimating Respondent Cost

(i)

Estimating Labor Costs

Estimates for respondent labor costs were prepared using industry-specific labor rates
identical to those used for the cost model in the rulemaking and are assumed to be $50/hour.
Annual labor costs for permittees are, therefore, estimated as follows:
($50/hour)*(40 hours/site/year) = $2,000/site/year
Similarly, annual labor costs for NPDES-authorized States are as follows:
($50/hour)*(4.5 hours/site/year) = $225/site/year
(ii)

Operations and Maintenance (O&M) Costs

The Agency assumes no O&M costs due to the fact that effluent treatment systems usage
at construction sites is on a rental basis and all monitoring equipment costs are subsumed within
the leasing arrangements and, therefore, not directly borne by the sites.
6(c)

Estimating Agency Burden and Cost

EPA burden is based on management and support activities for construction sites located
in the following:
C

States without NPDES authority: EPA activities include analysis of monitoring
data and review of DMRs (12 total construction sites); this would translate to an
incremental burden in addition to current activities. Recurring incremental EPA
burden for processing and analyzing monitoring data, including entry into the
PCS database (reporting and recordkeeping), is estimated to be 30 minutes (0.5
hour) per site per DMR. In addition, EPA assumes that approximately 10 percent
of all DMRs submitted will require follow-up action, with an estimated burden of
one hour per DMR.

C

States with NPDES control authority: EPA activities include program support,
such as review of NPDES permit renewal applications and draft permits, and
review of monitoring data (5,583 total construction sites). To estimate Agency
burden support activities, EPA assumes that approximately 10 percent of all
DMRs submitted will require follow-up assistance from EPA with an estimated
burden of one hour per DMR.

Burden Statement

EPA estimates that there are 5,595 affected construction sites in the Construction and
Development Point Source Category. These sites will perform additional sample collection and
pollutant analyses and reporting and recordkeeping to permit authorities, as part of NPDES
permit requirements. EPA estimates affected sites to incur a burden of 223,800 hours per year
12

Turbidity Monitoring Requirements for Construction Sites

for these activities, corresponding to a cost of $11,190,000. On a per-site basis, sites are
anticipated to incur an average of 40 hours per year for sampling, reporting and recordkeeping
for monthly DMRs for an average annual cost of $2,000.
NPDES-authorized States are estimated to incur 25,178 burden hours for processing and
analyzing monitoring data captured in submitted DMRs and for follow-up activities associated
with 10 percent of all DMRs submitted. This hourly burden translates to an estimated
$1,258,900 annually for these activities.
EPA burden is estimated to be 5,090 hours per year for support of State follow-up
activities, as well as acting as the NPDES permit authority for 12 sites where the States are not
authorized NPDES authorities at a cost of $254,500.
Burden means the total time, effort, or financial resources expended by persons to
generate, maintain, retain, or disclose or provide information to or for a federal agency. This
includes the time needed to review instructions; develop, acquire, install, and utilize technology
and systems for the purposes of collecting, validating, and verifying information, processing and
maintaining information, and disclosing and providing information; adjust the existing ways to
comply with any previously applicable instructions and requirements; train personnel to be able
to respond to a collection of information; search data sources; complete and review the collection
of information; and transmit or otherwise disclose the information. An agency may not conduct
or sponsor, and a person is not required to respond to, a collection of information unless it
displays a currently valid OMB control number. The OMB control numbers for EPA’s
regulations are listed in 40 CFR Part 9 and 48 CFR Chapter 15.
