Lighting Monitoring
Dredging occurred between June 6-November 8, 2011.
Click here to view lighting monitoring on the Quality of Life Monitoring Interactive Map. Monitoring was conducted daily during dredging operations. Phase 2 dredging will resume in spring 2012.

Legend:
Typical Operations: Lighting levels comply with the standard.
Control Level: Lighting level is above existing standard, although exceedance can be easily and immediately mitigated OR a project-related complaint is received from the public.
Exceedance Level: Recorded exceedance of the lighting standard is not easily and immediately mitigated OR frequent, recurrent complaints related to project activities.
Goal of the Standard
The goal of the lighting standard is to minimize the effects of project-related lighting on the quality of life in the surrounding communities.
What is the Standard?
The performance standard for lighting requires the monitoring of light levels at the beginning of any operations that could result in increased light levels compared to Phase 1 operations or compared to operations previously implemented in Phase 2, or in response to complaints. The standard varies with the type of area – rural and suburban, urban or commercial/industrial.
The performance standard for lighting sets the following limits:
| Location | Performance Standard | |
|---|---|---|
| Rural and suburban residential areas | 0.2 footcandle* | |
| Urban residential areas | 0.5 footcandle | |
| Commercial/Industrial areas | 1 footcandle | |
| *A measurement of light. | ||
Note: a 60-watt light bulb at 25 feet produces 0.1 footcandle
How Does the Standard Work?
- Monitoring at the beginning of any operations that could result in increased light levels compared to Phase 1 operations or compared to operations previously implemented in Phase 2, or in response to complaints.
- Receive, investigate and respond to complaints.
- Take action to minimize lighting impacts. For example, lighting at the dewatering facility and during dredging operations is directed toward work areas and away from neighboring properties.
- Reporting and notification by the cleanup team to EPA .
