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.
