Ranges from 56 to 77 feet (17 to 23.5 meters).
Continuing use, except as provided in paragraph (b)(4)(vi) of this section.
The designation in this paragraph (b)(4) sets forth conditions for the use of Central Long Island Sound (CLIS) and Western Long Island Sound (WLIS) Dredged Material Disposal Sites. These conditions apply to all disposal subject to the MPRSA, namely all federal projects and non-federal projects greater than 25,000 cubic yards. All references to “permittees” shall be deemed to include the Army Corps of Engineers (USACE) when it is authorizing its own dredged material disposal from a USACE dredging project. The conditions for this designation are as follows:
Disposal shall be limited to dredged material from Long Island Sound and vicinity.
Disposal shall comply with conditions set forth in the most recent approved Site Management and Monitoring Plan.
Except as provided in paragraphs (b)(4)(vi)(D) and (E) of this section, the disposal of dredged material at the CLIS and WLIS sites pursuant to this designation shall not be allowed beginning eight (8) years after July 5, 2005 unless a regional dredged material management plan (DMMP) for Long Island Sound has been completed by the North Atlantic Division of the USACE, in consultation with the State of New York, State of Connecticut and EPA, with a goal of reducing or eliminating the disposal of dredged material in Long Island Sound, and the EPA thereafter amends this site designation to incorporate procedures and standards that are consistent with those recommended in the DMMP. 1 Completion of the DMMP means finishing the items listed in the work plan (except for any ongoing long-term studies), including the identification of alternatives to open-water disposal, and the development of procedures and standards for the use of practicable alternatives to open-water disposal. If the completion of the DMMP does not occur within eight years of July 5, 2005 (plus any extensions under paragraphs (b)(4)(vi)(D) and (E) of this section), use of the sites shall be prohibited. However, if the DMMP is thereafter completed within one year, disposal of dredged material at the sites may resume.
1 If the EPA has acted in good faith to adopt substantially all procedures and standards for the use of the sites and the use of practicable alternatives to open-water disposal recommended in the DMMP, termination of the use of the sites based on the EPA not adopting all procedures and standards shall not occur unless a party first files a petition with the EPA pursuant to item 7 setting forth in detail each procedure or standard that the party believes the EPA must adopt in order to be consistent with the DMMP, and the EPA has an opportunity to act on the petition. Termination of the use of the sites shall not occur if in response to a petition the EPA determines that it has adopted substantially all procedures and standards for the use of the sites and the use of practicable alternatives to open-water disposal recommended in the DMMP, unless and until otherwise directed by a court. Termination of the use of the sites shall not occur based on not adopting a DMMP provision if the DMMP provision is not consistent with applicable law. Termination of the use of the sites shall not occur based on the EPA not meeting the 60 and 120 day rulemaking deadlines set forth in item 7, but use of the sites shall be suspended if the EPA misses either deadline, until the EPA issues a final rule. Termination of the use of the sites shall not occur based on the EPA adopting procedures and standards which are stricter than the recommendations of the DMMP.
The EPA may extend the eight-year deadline in paragraph (b)(4)(vi)(C) of this section for any reasonable period (on one or more occasions) if it obtains the written agreement of the USACE, the State of Connecticut (Department of Environmental Protection) and the State of New York (Department of State).
The EPA may extend the eight-year deadline in paragraph (b)(4)(vi)(C) of this section by up to one year (on one occasion only) if it determines in writing that the parties participating in the development of the DMMP have attempted in good faith to meet the deadline, but that the deadline has not been met due to factors beyond the parties' control (including funding). Such an extension may be in addition to any extension(s) granted under paragraph (b)(4)(vi)(D) of this section.
The EPA will conduct an annual review of progress in developing the DMMP. If the EPA finds that the DMMP is being unreasonably delayed by one or more parties, the EPA reserves the right to take the following actions as appropriate: (1) Suspend use of the sites even prior to the deadlines established in paragraphs (b)(4)(vi)(C) through (E) of this section through an amended rulemaking or (2) Exercise through rulemaking its statutory and regulatory authorities regarding designation of ocean disposal sites.
Upon completion of the DMMP, disposal of dredged material at the designated sites pursuant to the designation in this paragraph (b)(4) shall be allowed only from permittees that comply with procedures and standards consistent with the recommendations of the DMMP, and consistent with applicable law, for the use of the sites and for the use of practicable alternatives to open-water disposal, so as to reduce or eliminate the disposal of dredged material in Long Island Sound. Upon the completion of the DMMP, the EPA will within 60 days propose and within 120 days (subject to consideration of public comments) issue a legally binding amendment to the designation in this paragraph (b)(4) describing all such procedures and standards and specifying that they must be complied with as part of this designation. 2 If any party (or the EPA on its own initiative) is not satisfied that the final DMMP recommends sufficient procedures and standards to reduce or eliminate disposal of dredged material in Long Island Sound to the greatest extent practicable, or if any party is not satisfied with the EPA's amendment adopting such procedures and standards, the party may petition the EPA to do a rulemaking to amend the designation to establish different or additional standards. The EPA will act on any such petition within 120 days.
2 The EPA must preserve its discretion, in response to public comments, not to adopt such an amendment to this designation. The EPA understands that the State of New York has reserved its rights to revive its objection to this designation if the DMMP procedures and standards are not adopted.
Disposal not subject to the restrictions in paragraphs (b)(4)(vi)(C) through (G) or (b)(4)(vi)(I) of this section shall be permitted only for materials resulting from currently authorized or permitted dredging projects at Norwalk, Rye and New Rochelle. Such disposal must meet all applicable statutory and regulatory requirements. All phases of any of these project must be initiated within four (4) years from the date of the designation, or the project will become subject to paragraph (b)(4)(vi)(I) of this section.
Except for the projects covered by paragraph (b)(4)(vi)(H) of this section and until completion of the DMMP, disposal of dredged material at the designated sites pursuant to the designation in this paragraph (b)(4) shall be allowed only if, after full consideration of recommendations provided by an established Regional Dredging Team 3 (RDT), the USACE finds (and the EPA does not object to such finding), based on a fully documented analysis, that for a given dredging project:
3 A Regional Dredging Team (RDT) comprised of regulatory and coastal policy specialists from state and federal agencies will be formed.
There are no practicable alternatives (as defined in 40 CFR 227.16(b)) to open-water disposal in Long Island Sound and that any available practicable alternative to open-water disposal will be fully utilized for the maximum volume of dredged material practicable;
Determinations relating to paragraph (b)(4)(vi)(I)(1) of this section will recognize that any alternative to open-water disposal may add additional costs. Disposal of dredged material at the designated sites pursuant to this paragraph (b)(4) shall not be allowed if a practicable alternative is available. Any project subject to this restriction must be permitted or authorized prior to the completion of the DMMP and completed within two years after the completion of the DMMP.
Disposal shall be limited to dredged sediments that comply with the Ocean Dumping Regulations.
Disposal of dredged material at the designated sites pursuant to the designation in this paragraph (b)(4) shall not be allowed for any materials subject to a waiver under 33 U.S.C. 1413(d) unless, for any project where a waiver is sought, the New England or New York District of the USACE provides notification, by certified mail at least thirty (30) days before making the waiver request, to the Governors of the states of Connecticut and New York and the North Atlantic Division of the USACE that it will be requesting a waiver.
Transportation of dredged material to the sites shall only be allowed when weather and sea conditions will not interfere with safe transportation and will not create risk of spillage, leak or other loss of dredged material in transit. No disposal trips shall be initiated when the National Weather Service has issued a gale warning for local waters during the time period necessary to complete dumping operations.
The parties participating in the DMMP will need to seek additional funding in order to develop the DMMP. Nothing in the designation in this paragraph (b)(4) or elsewhere guarantees that any agency will be able to obtain funding for the DMMP. This designation shall not be interpreted as or constitute a commitment that the United States will obligate or expend funds in contravention of the Anti-Deficiency Act, 31 U.S.C. 1341. Rather, the sole remedy for any failure to meet the conditions specified in this paragraph (b)(4)(vi) shall be the restriction of the authority to dispose of dredged material, as provided in this paragraph (b)(4).
Nothing in the designation in this paragraph (b)(4) or elsewhere precludes the EPA from exercising its statutory authority to designate other ocean disposal sites, not subject to the restrictions in paragraph (b)(4)(vi), or taking any subsequent action to modify the site designation in paragraph (b)(4), provided that the EPA makes any such designation or takes such subsequent action through a separate rulemaking in accordance with all applicable legal requirements. Nothing in this designation shall be interpreted to restrict the EPA's authorities under the MPRSA or the implementing regulations or to amend the implementing regulations.

Restrictions/provisions:
The remainder of this § 228.15(l)(3) (hereinafter referred to as “this section”) constitutes the required Site Management and Monitoring Plan (SMMP) for the SF-DODS. This SMMP shall be supplemented by a Site Management and Monitoring Plan Implementation Manual (SMMP Implementation Manual) containing more detailed operational guidance. The SMMP Implementation Manual may be periodically revised as necessary; proposed revisions to the SMMP Implementation Manual shall be made following opportunity for public review and comment. Adherence to the provisions of the most current SMMP Implementation Manual, including mandatory permit conditions, site monitoring activities, and any other condition(s) EPA or the Corps have required as part of the project authorization or permit, is a requirement for use of the SF-DODS. SF-DODS use shall be subject to the following restrictions and provisions:
Type and capacity of disposed materials.
Site disposal capacity is 4.8 million cubic yards of suitable dredged material per year for the remaining period of site designation. This limit is based on considerations in the regional Long Term Management Strategy for the placement of dredged material within the San Francisco Bay region, and on monitoring of site use since the SF-DODS was designated in 1994.
Permit/project conditions.
Paragraph (l)(3)(viii)(A) of this section sets forth requirements for inclusion in permits to use the SF-DODS, and in all Army Corps of Engineers federal project authorizations. Paragraph (l)(3)(viii)(B) of this section describes additional project-specific conditions that will be required of disposal permits and operations as appropriate. Paragraph (l)(3)(viii)(C) of this section describes how alternative permit conditions may be authorized by EPA and the Corps of Engineers. All references to “permittees” shall be deemed to include the Army Corps of Engineers when implementing a federal dredging project.
All permits or federal project authorizations authorizing use of the SF-DODS shall include the following conditions, unless approval for an alternative permit condition is sought and granted pursuant to paragraph (l)(3)(viii)(C) of this section:
(1) Transportation of dredged material to the SF-DODS shall only be allowed when weather and sea state conditions will not interfere with safe transportation and will not create risk of spillage, leak or other loss of dredged material in transit to the SF-DODS. No disposal trips shall be initiated when the National Weather Service has issued a gale warning for local waters during the time period necessary to complete dumping operations, or when wave heights are 16 feet or greater. The permittee must consult the most current version of the SMMP Implementation Manual for additional restrictions and/or clarifications regarding other sea state parameters, including, but not limited to wave period.
(2) All vessels used for dredged material transportation and disposal must be loaded to no more than 80 percent by volume of the vessel. Before any disposal vessel departs for the SF-DODS, an independent quality control inspector must certify in writing that the vessel meets the conditions and requirements of a certification checklist that contains all of the substantive elements found in the example contained in the most current SMMP Implementation Manual. For the purposes of paragraph (l)(3)(viii) of this section, “independent” means not an employee of the permittee or dredging contractor; however, the Corps of Engineers may provide inspectors for Corps of Engineers dredged material disposal projects.
(3) Dredged material shall not be leaked or spilled from disposal vessels during transit to the SF-DODS.
(4) Disposal vessels in transit to and from the SF-DODS should remain at least three nautical miles from the Farallon Islands whenever possible. Closer approaches should occur only in situations where the designated vessel traffic lane enters the area encompassed by the 3-mile limit, and where safety may be compromised by staying outside of the 3-mile limit. In no case may disposal vessels leave the designated vessel traffic lane.
(5) When dredged material is discharged within the SF-DODS, no portion of the vessel from which the materials are to be released (e.g., hopper dredge or towed barge) can be further than 1,900 feet (600 meters) from the center of the target area at 37°39′ N, 123°29′ W.
(6) No more than one disposal vessel may be present within the permissible dumping target area referred to in paragraph (l)(3)(viii)(A)(5) of this section at any time.
(7) Disposal vessels shall use an appropriate navigation system capable of indicating the position of the vessel carrying dredged material (for example, a hopper dredged vessel or towed barge) with a minimum accuracy and precision of 100 feet during all disposal operations. The system must also indicate the opening and closing of the doors of the vessel carrying the dredged material. If the positioning system fails, all disposal operations must cease until the navigational capabilities are restored. The back-up navigation system, with all the capabilities listed in this condition, must be in place on the vessel carrying the dredged material.
(8) The permittee shall maintain daily records of the amount of material dredged and loaded into barges for disposal, the times that disposal vessel depart for, arrive at and return from the SF-DODS, the exact locations and times of disposal, and the volumes of material disposed at the SF-DODS during each vessel trip. The permittee shall further record wind and sea state observations at intervals to be established in the permit.
(9) For each disposal vessel trip, the permittee shall maintain a computer printout from a Global Positioning System or other acceptable navigation system showing transit routes and disposal coordinates, including the time and position of the disposal vessel when dumping was commenced and completed.
(10) An independent quality control inspector (as defined in paragraph (l)(3)(viii)(A)(2)) of this section shall observe all dredging and disposal operations. The inspector shall verify the information required in paragraphs (l)(3)(viii)(A)(8) and (9) of this section. The inspector shall promptly inform permittees of any inaccuracies or discrepancies concerning this information and shall prepare summary reports, which summarize all such inaccuracies and discrepancies, from time to time as shall be specified in permits. Such summary reports shall be sent by the permittee to the District Engineer and the Regional Administrator within a time interval that shall be specified in the permit.
(11) The permittee shall report any anticipated or actual permit violations to the District Engineer and the Regional Administrator within 24 hours of discovering such violation. If any anticipated or actual permit violations occur within the Gulf of the Farallones or the Monterey Bay National Marine Sanctuaries, the permittee must also report any such violation to the respective Sanctuary Manager within 24 hours. In addition, the permittee shall prepare and submit reports, certified accurate by the independent quality control inspector, on a frequency that shall be specified in permits, to the District Engineer and the Regional Administrator setting forth the information required by Mandatory Conditions in paragraphs (l)(3)(viii)(A)(8) and (9) of this section.
(12) Permittees, and the Corps in its Civil Works projects, must make arrangements for independent observers to be present on disposal vessels for the purpose of conducting shipboard surveys of seabirds and marine mammals. Observers shall employ standardized monitoring protocols, as referenced in the most current SMMP Implementation Manual. At a minimum, permittees shall ensure that independent observers are present on at least one disposal trip during each calendar month that disposal occurs, AND on average at least once every 25 vessel trips to the SF-DODS.
(13) At the completion of short-term dredging projects, at least annually for ongoing projects, and at any other time or interval requested by the District Engineer or Regional Administrator, permittees shall prepare and submit to the District Engineer and Regional Administrator a report that includes complete records of all dredging, transport and disposal activities, such as navigation logs, disposal coordinates, scow certification checklists, and other information required by permit conditions. Electronic data submittals may be required to conform to a format specified by the agencies. Permittees shall include a report indicating whether any dredged material was dredged outside the areas authorized for dredging or was dredged deeper than authorized for dredging by their permits.
Permits or federal project authorizations authorizing use of the SF-DODS may include the following conditions, if EPA determines these conditions are necessary to facilitate safe use of the SF-DODS, the prevention of potential harm to the environment or accurate monitoring of site use:
(1) Permittees may be required to limit the speed of disposal vessels in transit to the SF-DODS to a rate that is safe under the circumstances and will prevent the spillage of dredged materials.
(2) Permittees may be required to use automated data logging systems for recording navigation and disposal coordinates and/or load levels throughout disposal trips when such systems are feasible and represent an improvement over manual recording methodologies.
(3) Any other conditions that EPA or the Corps of Engineers determine to be necessary or appropriate to facilitate compliance with the requirements of the MPRSA and this section may be included in site use permits.
Alternative permit/project conditions.
Alternatives to the permit conditions specified in paragraph (l)(3)(viii) of this section in a permit or federal project authorization may be authorized if the permittee demonstrates to the District Engineer and the Regional Administrator that the alternative conditions are sufficient to accomplish the specific intended purpose of the permit condition in issue and further demonstrates that the waiver will not increase the risk of harm to the environment, the health or safety of persons, nor will impede monitoring of compliance with the MPRSA, regulations promulgated under the MPRSA, or any permit issued under the MPRSA.
Data shall be collected in accordance with a three-tiered site monitoring program which consists of three interdependent types of monitoring for each tier: Physical, chemical and biological. In addition, periodic confirmatory monitoring concerning potential site contamination shall be performed. Specific guidance for site monitoring tasks required by this paragraph shall be described in a Site Management and Monitoring Implementation Manual (SMMP Implementation Manual) developed by EPA. The SMMP Implementation Manual shall be reviewed periodically and any necessary revisions to the Manual will be issued for public review under an EPA Public Notice.
Tier 1 monitoring activities.
Tier 1 monitoring activities shall consist of the following:
(1) Physical monitoring. Tier 1 Physical Monitoring shall consist of a physical survey to map the area on the seafloor within and in the vicinity of the disposal site where dredged material has been deposited (the footprint). Such a survey shall use appropriate technology (for example, sediment profile photography) to determine the areal extent and thickness of the disposed dredged material, and to determine if any dredged material has deposited outside of the disposal site boundary.
(2) Chemical monitoring. Tier 1 Chemical Monitoring shall consist of collecting, processing, and preserving boxcore samples of sediments so that such sediments could be subjected to sediment chemistry analysis in the appropriate tier. Samples shall be collected within the dredged material footprint, outside of the dredged material footprint, and outside of the disposal site boundaries. Samples within the footprint shall be subjected to chemical analysis in annual Tier 1 activity. Samples from outside of the footprint and outside of the disposal site boundaries shall be archived and analyzed only when the criteria requiring Tier 2 as specified in paragraph (l)(3)(x) of this section are met. A sufficient number of samples shall be collected so that the potential for adverse impacts due to elevated chemistry can be assessed with an appropriate time-series or ordinal technique.
(3) Biological monitoring. Tier 1 Biological Monitoring shall have two components: Monitoring of pelagic communities and monitoring of benthic communities.
(i) Pelagic communities. Tier 1 Biological Monitoring shall include regional surveys of seabirds, marine mammals and mid-water column fish populations appropriate for evaluating how these populations might be affected by disposal site use. A combination of annual regional and periodic (random) shipboard surveys of seabirds and marine mammals will be used. The regional survey designs for each category of biota shall be similar to that used for the regional characterization studies referenced in the Final Environmental Impact Statement for Designation of a Deep Water Ocean Dredged Material Disposal Site off San Francisco, California (August 1993) with appropriate realignments to accommodate transects within and in the vicinity of the SF-DODS. The periodic shipboard surveys shall be performed from vessels involved in dredged material disposal operations at the SF-DODS as specified in permit conditions imposed pursuant to paragraph (l)(3)(viii)(A)(12) of this section. The minimum number of surveys must be sufficient to characterize the disposal operations for each project, and, as practicable, provide seasonal data for an assessment of the potential for adverse impacts for the one-year period. An appropriate time-series (ordinal), and community analysis shall be performed using data collected during the current year and previous years.
(ii) Benthic communities. Tier 1 Biological Monitoring shall include collection and preservation of boxcore samples of benthic communities so that such samples could be analyzed as a Tier 2 activity.
(4) Annual reporting. The results of the annual Tier 1 studies shall be compiled in an annual report which will be available for public review.
(B) Tier 2 monitoring activities. Tier 2 monitoring activities shall consist of the following:
(1) Physical monitoring. Tier 2 Physical Monitoring shall consist of oceanographic studies conducted to validate and/or improve the models used to predict the dispersion in the water column and deposition of dredged material on the seafloor at the SF-DODS. The appropriate physical oceanographic studies may include: The collection of additional current meter data, deployment of sediment traps, and deployment of surface and subsurface drifters.
(2) Chemical monitoring. Tier 2 Chemical Monitoring shall consist of performing sediment chemistry analysis on samples collected and preserved in Tier 1 from outside of the footprint and outside of the disposal site boundaries.
(3) Biological monitoring. Tier 2 Biological Monitoring shall involve monitoring of pelagic communities and monitoring of benthic communities.
(i) Pelagic communities. Tier 2 Biological Monitoring for pelagic communities shall include supplemental surveys of similar type to those in Tier 1, or other surveys as appropriate.
(ii) Benthic communities. Tier 2 Biological Monitoring for benthic communities shall include a comparison of the benthic community within the dredged material footprint to benthic communities in adjacent areas outside of the dredged material footprint. An appropriate time-series (ordinal) and community analysis shall be performed using data collected during the current year and previous years to determine whether there are adverse changes in the benthic populations outside of the disposal site which may endanger the marine environment.
(4) Annual reporting. The results of any required Tier 2 studies shall be compiled in an annual report which will be available for public review.
Tier 3 monitoring activities.
Tier 3 monitoring activities shall consist of the following:
(1) Physical monitoring. Tier 3 physical monitoring shall consist of advanced oceanographic studies to study the dispersion of dredged material in the water column and the deposition of dredged material on the seafloor in the vicinity of the SF-DODS. Such physical monitoring may include additional, intensified studies involving the collection of additional current meter data, deployment of sediment traps, and deployment of surface and subsurface drifters. Such studies may include additional sampling stations, greater frequency of sampling, more advanced sampling methodologies or equipment, or other additional increased study measures compared to similar studies conducted in Tier 1 or 2.
(2) Chemical monitoring. Tier 3 Chemical Monitoring shall consist of analysis of tissues of appropriate field-collected benthic and/or epifaunal organisms to determine bioaccumulation of contaminants that may be associated with dredged materials deposited at the SF-DODS. Sampling and analysis shall be designed and implemented to determine whether the SF-DODS is a source of adverse bioaccumulation in the tissues of benthic species collected at or outside the SF-DODS, compared to adjacent unimpacted areas, which may endanger the marine environment. Appropriate sampling methodologies for these tests will be determined and the appropriate analyses will involve the assessment of benthic body burdens of contaminants and correlation with comparison of the benthic communities inside and outside of the sediment footprint.
(3) Biological monitoring. Tier 3 biological monitoring shall have two components: monitoring of pelagic communities and monitoring of benthic communities.
(i) Pelagic communities. Tier 3 Biological Monitoring shall include advanced studies of seabirds, marine mammals and mid-water column fish to evaluate how these populations might be affected by disposal site use. Such studies may include additional sampling stations, greater frequency of sampling, more advanced sampling methodologies or equipment, or other additional increased study measures compared to similar studies conducted in Tier 1 or 2. Studies may include evaluation of sub-lethal changes in the health of pelagic organisms, such as the development of lesions, tumors, developmental abnormality, decreased fecundity or other adverse sub-lethal effect.
(ii) Benthic communities. Tier 3 Biological Monitoring shall include advanced studies of benthic communities to evaluate how these populations might be affected by disposal site use. Such studies may include additional sampling stations, greater frequency of sampling, more advanced sampling methodologies or equipment, or other additional increased study measures compared to similar studies conducted in Tier 2. Studies may include evaluation of sub-lethal changes in the health of benthic organisms, such as the development of lesions, tumors, developmental abnormality, decreased fecundity or other adverse sub-lethal effect.
(4) Reporting. The results of any required Tier 3 studies shall be compiled in a report which will be available for public review.
Periodic confirmatory monitoring.
At least once every three years, the following confirmatory monitoring activities will be conducted and results compiled in a report which will be available for public review: Samples of sediments taken from the dredged material footprint shall be subjected to bioassay testing using one or more appropriate sensitive marine species consistent with applicable ocean disposal testing guidance (“Green Book” or related Regional Implementation Agreements), as determined by the Regional Administrator, to confirm whether contaminated sediments are being deposited at the SF-DODS despite extensive pre-disposal testing. In addition, near-surface arrays of appropriate filter-feeding organisms (such as mussels) shall be deployed in at least three locations in and around the disposal site for at least one month during active site use, to confirm whether substantial bioaccumulation of contaminants may be associated with exposure to suspended sediment plumes from multiple disposal events. One array must be deployed outside the influence of any expected plumes to serve as a baseline reference.
Site management actions.
Once disposal operations at the site begin, the three-tier monitoring program described in paragraphs (l)(3)(ix) (A) through (C) of this section shall be implemented on an annual basis, through December 31, 1998, independent of the actual volumes disposed at the site. Thereafter, the Regional Administrator may establish a minimum annual disposal volume (not to exceed 10 percent of the designated site capacity at any time) below which this monitoring program need not be fully implemented. The Regional Administrator shall promptly review monitoring reports for the SF-DODS along with any other information available to the Regional Administrator concerning site monitoring activities. If the information gathered from monitoring at a given monitoring tier is not sufficient for the Regional Administrator to base reasonable conclusions as to whether disposal at the SF-DODS might be endangering the marine ecosystem, then the Regional Administrator shall require intensified monitoring at a higher tier. If monitoring at a given tier establishes that disposal at the SF-DODS is endangering the marine ecosystem, then the Regional Administrator shall require modification, suspension or termination of site use.
Selection of site monitoring tiers—
(1) Physical monitoring. Physical monitoring shall remain limited to Tier 1 monitoring when Tier 1 monitoring establishes that no significant amount of dredged material has been deposited or transported outside of the site boundaries. Tier 2 monitoring shall be employed when Tier 1 monitoring is insufficient to conclude that a significant amount of dredged material as defined in paragraph (l)(3)(x)(A)(4) of this section has not been deposited or transported outside of the site boundaries.
(2) Chemical monitoring. (i) Chemical monitoring shall remain limited to Tier 1 Chemical Monitoring when the results of Physical Monitoring indicate that a significant amount of dredged material as defined in paragraph (l)(3)(x)(A)(4) of this section has not been deposited or transported off-site, and Tier 1 Chemical Monitoring establishes that dredged sediments deposited at the disposal site do not contain levels of chemical contaminants that are significantly elevated above the range of chemical contaminant levels in dredged sediments that the Regional Administrator and the District Engineer found to be suitable for disposal at the SF-DODS pursuant to 40 CFR part 227.
(ii) Tier 2 monitoring shall be employed when the results of Physical Monitoring indicate that a significant amount of dredged material as defined in paragraph (l)(3)(x)(A)(4) of this section has been deposited off-site, and Tier 1 Chemical Monitoring is insufficient to establish that dredged sediments deposited at the disposal site do not contain levels of chemical contaminants that are significantly elevated above the range of chemical contaminant levels in dredged sediments that the Regional Administrator and the District Engineer found to be suitable for disposal at the SF-DODS pursuant to 40 CFR part 227.
The Regional Administrator may employ Tier 2 monitoring when available evidence indicates that a significant amount of dredged material as defined in paragraph (l)(3)(x)(A)(4) of this section has been deposited near the SF-DODS site boundary.
(iii) Tier 3 monitoring shall be employed within and outside the dredged material footprint when Tier 2 Chemical Monitoring is insufficient to establish that dredged sediments deposited at the disposal site do not contain levels of chemical contaminants that are significantly elevated above the range of chemical contaminant levels in dredged sediments that the Regional Administrator and the District Engineer found to be suitable for disposal at the SF-DODS pursuant to 40 CFR part 227.
(3) Biological monitoring. (i) Pelagic communities. Biological monitoring for pelagic communities shall remain limited to Tier 1 monitoring when Tier 1 monitoring establishes that disposal at the SF-DODS has not endangered the monitored pelagic communities. When Tier 1 monitoring is insufficient to make reasonable conclusions whether disposal at the site has endangered the monitored pelagic communities, then Tier 2 monitoring of pelagic communities shall be employed. When Tier 2 monitoring is insufficient to make reasonable conclusions whether disposal at the site has endangered the monitored pelagic communities, then Tier 3 monitoring of pelagic communities shall be employed.
(ii) Benthic communities. Biological monitoring for benthic communities shall remain limited to Tier 1 monitoring when physical monitoring establishes that a significant amount of dredged material has not been deposited outside of the site boundaries. If physical monitoring indicates that a significant amount of dredged material has been deposited or transported outside of the site boundaries, then Tier 2 analysis of benthic communities shall be performed. If Chemical Monitoring establishes that there is significant bioaccumulation of contaminants in organisms sampled from within or outside the dredged material footprint, then Tier 3 Biological Monitoring of the disposal site shall be employed. Tier 3 Biological Monitoring may replace Tier 3 Chemical Monitoring if observed biological effects are established as surrogate indicators for bioaccumulation of chemical contaminants in sampled organisms.
(4) Definition of significant dredged material accumulation. For purposes of this paragraph (l)(3)(x)(A) of this section, dredged material accumulation on the ocean bottom to a thickness of five centimeters shall be considered to be a significant amount of dredged material. The Regional Administrator may determine that a lesser amount of accumulation is significant if available evidence indicates that a lesser amount of off-site accumulation could endanger marine resources.
Modification, suspension or termination of site use.
(1) If the results of site monitoring or other information indicate that any of the following are occurring as a result of disposal at the SF-DODS, then the Regional Administrator shall modify, suspend, or terminate site use overall, or for individual projects as appropriate:
(i) Exceedance of Federal marine water quality criteria within the SF-DODS following initial mixing as defined in 40 CFR 227.29(a) or beyond the site boundary at any time;
(ii) Placement or movement of significant quantities of disposed material outside of site boundaries near or toward significant biological resource areas or marine sanctuaries;
(iii) Endangerment of the marine environment related to potentially significant adverse changes in the structure of the benthic community outside the disposal site boundary;
(iv) Endangerment to the health, welfare, or livelihood of persons or to the environment related to potentially significant adverse bioaccumulation in organisms collected from the disposal site or areas adjacent to the site boundary compared to the reference site;
(v) Endangerment to the health, welfare, or livelihood of persons related to potentially significant adverse impacts upon commercial or recreational fisheries resources near the site; or
(vi) Endangerment to the health, welfare, or livelihood of persons or to the environment related to any other potentially significant adverse environmental impacts.
(2) The Regional Administrator shall modify site use, rather than suspend or terminate site use, when site use modification will be sufficient to eliminate the adverse environmental impacts referred to in paragraphs (l)(3)(x)(B)(1) (i) or (ii) of this section or the endangerment to human health, welfare or livelihood to the environment referred to in paragraphs (l)(3)(x)(B)(1) (iii) through (vi) of this section. Notwithstanding the provisions of any permit or federal project authorization authorizing site use, the Regional Administrator shall order, following opportunity for public comment, any of the following modifications to site use that he or she deems necessary to eliminate the adverse environmental effect or endangerment to human health, welfare, or livelihood or to the environment:
(i) Change or additional restrictions upon the permissible times, rates and total volume of disposal of dredged material at the SF-DODS;
(ii) Change or additional restrictions upon the method of disposal or transportation of dredged materials for disposal; or
(iii) Change or additional limitations upon the type or quality of dredged materials according to chemical, physical, bioassay toxicity, or bioaccumulation characteristics.
(3) The Regional Administrator shall suspend site use when site use suspension is both necessary and sufficient to eliminate any adverse environmental effect or endangerment to human health, welfare, or livelihood or to the environment referred to in paragraph (l)(3)(x)(B)(1) of this section. Notwithstanding the provisions of any permit or federal project authorization authorizing site use, the Regional Administrator shall order, following opportunity for public comment, site use suspension until an appropriate management action is identified or for a time period that will eliminate the adverse environmental effect or endangerment to human health, welfare, or livelihood or to the environment.
(4) Notwithstanding the provisions of any permit or federal project authorization authorizing site use, the Regional Administrator shall order, following opportunity for public comment, site use permanently terminated if this is the only means for eliminating the adverse environmental impacts referred to in paragraphs (l)(3)(x)(B)(1) (i) or (ii) of this section or the endangerment to human health, welfare or livelihood to the environment referred to in paragraphs (l)(3)(x)(B)(1) (iii) through (vi) of this section.
