TECHNICAL MANUAL: VOLUME 03

Overhead Utility & Environmental Safety Code

Federal and municipal safety standards detailing JEA overhead line radial boundaries, FDEP coastal dune buffers, and EPA closed-containment washout logs.

1. JEA Power Line Radial Limits

Staging a concrete boom pump under or near energized electrical transmission lines poses extreme arc flash hazards. Under OSHA 1926.1408, the boom tip, flexible hoses, and support wires must maintain a strict radial safety envelope.

Engineering Blueprint — Spec Sheet #03-A
OSHA Radial Clearance
JEA 50kV LINE 10-FT MIN RADIAL
EPA Washout Bag System
Woven polypropylene concrete washout bag staged on-site filled with gray slurry, preventing sand runoff
Closed-Containment Seal

Standard JEA/OSHA regulatory clearance zones relative to lines carrying active voltage:

Line Voltage (Phase-to-Ground) OSHA Radial Limit Staging Precaution
Standard Residential Drop (Up to 50kV) 10-Foot Radial Clearance Dedicated spotter mandatory during boom extension
High-Voltage Substation Feeder (50kV - 200kV) 15-Foot Radial Clearance Pre-staging utility plan filed with JEA engineering
Regional High-Voltage Grid (200kV - 350kV) 20-Foot Radial Clearance Line de-energization or insulating blankets required

2. Florida EPA Washout Compliance

Concrete washout wastewater is highly toxic. Under EPA and Florida Department of Environmental Protection (FDEP) rules, concrete slurry can never be discharged directly into Florida soils or stormwater networks.

Standard jobsites must establish a plastic-lined washout pit or utilize portable closed-containment washout bag systems. If a washout area is not provided by the builder, our operators will deploy water-tight containment bags for aggregate capture. We bag and transport all wash slurries off-site for certified commercial disposal.

Compliance Warning: Direct washout discharge into JEA storm drains carries municipal fines exceeding $10,000 per violation. Coastal locations near St. Augustine and Fernandina Beach beaches are subject to immediate FDEP stop-work audits if slurry comes into contact with sandy shorelines.

3. Coastal Dune Setback Limits

Beachfront structural placements (such as Ponte Vedra custom home slab additions or Fernandina Beach seawalls) are highly regulated. Concrete pumping operations must stage equipment completely landward of the FDEP beach construction setback lines.

To protect fragile dune vegetation and nesting turtles, our operators run flexible ground slicklines past narrow access side paths, keeping all heavy trucks staged curbside on solid asphalt, clear of sensitive dune sand zones.

Common Questions

Power Lines & Washout FAQ

How close can a concrete boom pump work to overhead power lines? +
Per OSHA 1926.1408 and local utility safety guidelines, boom equipment must maintain a minimum 10-foot radial clearance from active lines up to 50kV, increasing to 20 feet or de-energization for higher-voltage transmission lines. A certified spotter tracks boom-tip position relative to any nearby lines on every job.
Is it illegal to dump concrete washout on the ground or in a storm drain? +
Yes. Under EPA and Florida Department of Environmental Protection (FDEP) rules, discharging concrete washout slurry directly into storm drains, soil, or waterways is prohibited and can carry real fines. Washout must be contained in a lined pit or portable containment system and disposed of properly.
Who is responsible for providing a washout containment area? +
The general contractor or property owner typically provides a plastic-lined washout pit or designated containment area on-site. If one isn't available when we arrive, we can deploy a portable washout containment bag for an additional environmental fee rather than delay or skip proper disposal.
Do I need a permit to stage a concrete pump on a public street? +
Yes, if the rig will occupy a public street, parking lane, or municipal sidewalk, a Right-of-Way (ROW) permit from the local Permit Center is required. Staging entirely on private property generally doesn't require a ROW permit. We help coordinate this with GCs ahead of dispatch day.
Does a power line have to be de-energized before a boom pump can work near it? +
Not always — standard distribution lines up to 50kV can typically be worked near safely by maintaining the required 10-foot radial clearance. De-energization is generally reserved for higher-voltage transmission lines where the required clearance (up to 20 feet) can't be maintained given the site's layout. The utility company makes the final call on de-energization requests.
What are the setback rules for pumping near coastal dunes? +
Coastal construction near protected dune systems is subject to state and local setback regulations that limit how close equipment and washout containment can be positioned relative to the dune line. We coordinate staging plans with your GC or coastal engineer ahead of beachside jobs to keep equipment clear of protected areas.
