a. The likelihood of sea turtles and marine mammals being in the blasting area. TheCONTRACTOR shall consult existing scientific literature and the FWC and/or otherresource agencies. Pre-blast marine mammal/sea turtle surveys may be required, at thediscretion of the FWC, USFWS, NMFS, or other reviewing/permitting agencies.

b. A description of the marine mammal/sea turtle “exclusion zone” that will be developedand used for underwater blasting programs to provide species’ protection. The preferredminimum exclusion zone radius or range from which to protect marine mammal/seaturtles is 500 linear feet beyond the perimeter of placed blasting agents for a shot. Thepreferred maximum exclusion zone is a 2,000-foot radius beyond the blast perimeter for asubmerged shot. An additional 500 feet should be added to the calculated radius orexclusion zone in order to adequately control animals being precluded from this area.When underwater blasting will be conducted in a very controlled manner for a protractedperiod of months and has acceptable project monitoring, the CONTRACTOR may applyto the FWC and other appropriate permitting agencies for a special review of exclusionzone criteria.

Underwater explosions can be broadly categorized as either “confined” or “open-water.”Confined shots produce much less environmental damage for the same charge weightwhen compared to open-water shots. For confined shots, the pressure waves aredominantly radiated into a stiff medium (such as rock or a massive structure founded onrock) and remain in that medium. Confined shots have vertical heights of the stiffmedium exposed to water (or loose sediment below water) of less than half the smallerareal (horizontal) dimension of removal. Blasting in the water column, not connected to astructure, has a high transmission of pressure waves through the water column. Blastremoval of some stiff-medium structures below the water surface (e.g., columns, piers, orpilings) releases its energy directly to the surrounding water column or loose sediment,which has a high transmission of pressure waves through the water column. Underwater


blasting with high transmission to the water column and, thus potentially high organismimpact, shall be termed open-water blasting.

The “exclusion zone”, also referred to as the “watch zone” shall be calculated using thefollowing methods, appropriate to the type of blasting:

Open Water Blasting

The exclusion zone for open-water blasting shall be determined from the open-watershot’s maximum charge weight per delay, with an additional buffer of 500 feet. For anopen-water shot’s maximum charge weight per delay of less than 0.19 pound, theexclusion-zone radius of 300 linear feet applies. The maximum charge weight per delayof a confined shot shall not exceed 57 pounds for the exclusion-zone criterion beneath thewaters of the State of Florida, because the exclusion-zone radius would be greater than2,000 linear feet. The equation for the open-water blasting exclusion-zone radius, EZOW,for maximum charge weights per delay between 0.19 to 57 pounds is:

EZOW (feet) = (520 w1/3)(2) + 500 feet,

where w is the maximum charge weight (in pounds) per delay of an individual openwatershot.

Confined Blasting

The exclusion zone for confined blasting shall be determined from the confined shot’smaximum charge weight per delay, with an additional buffer of 500 feet. For a confinedshot’s maximum charge weight per delay of less than 1.5 pound, the “exclusion zone”radius of 500 linear feet applies. The maximum charge weight per delay of an open-watershot shall not exceed 450 pounds for the exclusion-zone criterion beneath the waters ofthe State of Florida, because the exclusion zone radius would be greater than 2,000 linearfeet. The equation for the confined blasting exclusion zone radius, EZC, for maximumcharge weights per delay between 1.5 to 450 pounds is:

EZOW (feet) = (520 w1/3) + 500 feet

Where w is the maximum charge weight (in pounds) per delay of an individual confinedshot.

c. A record of the type of underwater blasting (open-water or confined), procedures toreduce impacts, calculations of blast parameters, actual placement of explosive agents,organism exclusion zone distance calculations, and plans for observation shall be filedon-site before every shot is fired. Records for each shot of the blasting program shall beretained by the CONTRACTOR for the duration of project and made available to theFWC, USFWS, and NMFS immediately onsite or within two business days to thespecified mailing address, as requested.

The following records shall be kept for each placement position or boring: (1) - the upperand lower bounds of cemented or consolidated material to be removed or blasted; (2) -the weight of blasting agents and explosives, and their upper and lower bounds; (3) -stemming material appropriate for the size of the borehole; and (4) - upper and lowerbounds of the stemming placement within the cemented or consolidated material (usuallyrock or concrete). The record shall include the sequence of delays from the shortest tolongest individual delay time with the total weight of blasting agent at that delay time.The record keeping shall provide enough detail to allow interpretation of the quality ofshooting and level of compliance with the Blasting Plan.

d. A description of the monitoring program shall be implemented to record particlevelocities when a blasting position is within 1,000 feet of a land-based location. Particlevelocity monitoring independently confirms proper shot performance without the costand difficulty of either pressure-wave recording or organism testing. Reports of particlevelocity monitoring should be available to the FWC, USFWS, and NMFS, if requested,on the third business day following the shot.


Quantitative evaluation of potential marine mammal/sea turtle (i.e., manatee feedingareas, etc.) habitat that will be destroyed by the blasting project.

24. Mitigation Plan. The CONTRACTOR shall prepare a Mitigation Plan that shall include adetailed discussion of the measures employed to avoid or minimize the adverse impacts ofblasting. The following measures shall be included in the Mitigation Plan:

a. Blasting shall be conducted during the time when manatees, other marine mammals, andsea turtles are least likely to be in the blasting area. CONTRACTORs should consult withthe FWC, USFWS, and NMFS to determine the appropriate timing.

b. In tidal areas, the blasting CONTRACTOR shall conduct blasting during therecommended tidal phase deemed appropriate for the area (i.e., slack or low-tideconditions).

c. The volume and length of all blasting agents, detonation cord, and explosives will belimited to the minimum necessary to conduct the work in a manner that is efficient, safefor workers, and protective of aquatic and marine organisms.
