About this file
This document contains Project Design Criteria (PDCs) for in-water noise from pile and sheet pile installation in open water and confined space environments. The PDCs specify requirements for different types of pile installation activities, including trench and fill, pilot hole, jetting, vibratory, and impact hammer methods, as well as different pile materials and sizes.
The PDCs are categorized from A to E, with activities labeled A-D required to follow the corresponding PDCs, and activities labeled E excluded from the requirements. Key PDCs include limiting pile installations to daylight hours, observing for protected species, and implementing noise abatement measures such as bubble curtains or temporary noise attenuation piles for certain high-impact activities. The document also references a related federal contract opportunity, Solicitation Number 140P5424R0013, for the construction to replace the Fellers' Boathouse Dock at Canaveral National Seashore. This is a 100% Small Business Set-Aside with a proposal due date of 05/20/2024.

Project Design Criteria (PDCs) for In-Water Noise from Pile and Sheet Pile Installation
Open Water The letters A-E in the tables below specify the PDC category. Activities labeled A-D must follow the corresponding PDCs for labeled Category A-D below. Activities labeled E are excluded from this Opinion, as stated in Category E below.
Trenc h and fill
Pilot hole (auger or drop punch)
Jetting Vibratory Impact hamme r Wood piles 14-inch (in) diameter or less when installed via impact hammer and 36-in or less for all other installation methods
A
B
Concrete pile 24-in diameter/width or less in open water
A A A A B
Metal pipe pile 36-in diameter or less
A A A A E
2 metal boatlift I-beams A A A A B
Concrete slab wall- any size A A A A B
Vinyl sheet pile- any size A A A A B
Metal sheet pile- any size A A A A E
Confined Space
In Florida, we consider the confined space to be any area that has a solid object (e.g., shorelines or seawalls) within 150 ft of the pile installation site and in the U.S. Caribbean we consider confined space to be any area that has a solid object within 260 ft of the pile installation site.
Trenc h and fill
Pilot hole (auger or drop punch)
Jetting Vibratory Impact hamme r Wood pile 14-in diameter or less when installed via impact hammer and 36-in or less for all other installation methods

A. The Projects identified as A above must comply with PDCs identified for all projects in this Opinion. Specific PDCs related to noise include:
1. All work must occur during daylight hours only (PDC AP.6).
2. All construction personnel are responsible for observing water-related activities to detect the presence of these species and avoid them (PDC AP.7).
B. The projects identified as B above must follow all of the conditions under A, above, AND also must limit the maximum number of piles installed per day to no more than 10 piles per day.
C. The projects identified as C above must follow all of the conditions under A, above, AND also must limit the maximum number of piles installed per day to no more than 5 piles per day.
D. The projects identified as D above must follow all of the conditions under A and B, above, AND also must abide by one of the noise abatement measures below, as chosen by the applicant:
1. Bubble curtain: The bubble curtain design must adhere to the guidelines for unconfined and confined bubble curtains described in Appendix B.
2. Temporary noise attenuation pile (TNAP) also known as a pile isolation casing: The TNAP design must be constructed of a double-walled tubular casing (a casing within a larger casing), with at least a 5-in-wide area between the casings that is dewatered to create a hollow space or 5-in wide area between the casings completely filled with closed-cell foam or other noise dampening material between the walls. The TNAP must be long enough to be seated firmly on the sea bottom, fit over the pile being driven, and extend at least 3 ft above the surface of the water.
3. The use of any other alternative noise control method must receive prior approval by NMFS and the USACE, as described in Section 2.3.
E. The projects identified as E are not covered under this Opinion.
