Turbidity Monitoring Requirements for Construction Sites Regulated by the Effluent Limitations Guidelines and Standards for the Construction and Development Point Source Category (Final Rule)
Turbidity Monitoring
Requirements for Construction Sites Regulated by the Effluent
Limitations Guidelines and Standards for the Construction and
Development Point Source Category (Final Rule)
New
collection (Request for a new OMB Control Number)
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 burden and costs of the proposed guidelines
for the first three years after promulgation are 635,612 hours and
$22.1 million, affecting approximately 6,432 new and on-going
construction projects. The burden and costs are associated with the
monitoring and reporting requirements of the rule. These
requirements are being phased, and do not become effective until 18
months after promulgation, at which time the requirements will
apply to projects disturbing 20 or more acres. Four years after
promulgation, the monitoring and reporting requirements will apply
to projects disturbing 10 or more acres. As a result of the
phase-in of the requirements there are no affected projects during
the first year. However, during the second year, some on-going
projects from earlier years will be affected. Construction projects
vary considerably by start date and duration, with some projects
lasting more than one year. Please note that, for purposes of
burden and costs calculations, because of this project scheduling
and duration variability, there are an estimated 1,233 new and
on-going projects that are active at some point during year two and
5,199 during year three. These projects are estimated to generate
47,473 Discharge Monitoring Reports (DMRs) over the course of the
ICR approval period.
