300. SCOPE301. The USCG, USEPA, USDOI, USDOC and PRDNR agree that the primary method of controllingdischarged oil shall be the physical removal of the oil from the environment. These agencies recognizethat in certain instances the physical containment, collection, and removal of the oil may not be possible,and the effective use of dispersants or other chemical agents must be considered to prevent substantialthreat to public health or welfare, or minimize serious environmental damage. This Agreementestablishes criteria under which USEPA listed dispersants or chemical agents can be used on or in thewaters of the Commonwealth of Puerto Rico.400. PROTOCOLS401. As attested by the signatures set forth below, the USCG, USEPA, USDOI, USDOC, and thePRDNR agree that the pre-designated USCG On Scene Coordinator has pre-approval to order the use ofdispersants or chemical agents on oil discharges, as defined in the National Contingency Plan, when inthe judgement of the USCG On Scene Coordinator, the use of dispersants or chemical agents is necessaryto prevent substantial threat to public health or welfare, or minimize serious environmental damage,subject to the conditions presented in this document.402. The OSC shall arrive at his decision to use dispersants through the decision making process andinformation gathering scheme as detailed in Subpart J of the Caribbean Regional Contingency Plan(Annex K of the Local Spill Response Plan for Puerto Rico and the U.S. Virgin Islands).403. The USCG agrees with USEPA, USDOI, USDOC and PRDNR that if a decision has been madeto use dispersants under the provisions of this agreement, the OSC will immediately notify USEPA,USDOI, USDOC and PRDNR of that decision. This initial notification will include, but is not limited to,the following information to the extent available:a. Date, time, and location of the incident;b. Type and amount of oil discharged;c. Area affected;d. The projected area of impact of the oil if not dispersed;e. Reasons why dispersants or chemical agents have been selected;f. Type of dispersant to be used;g. Application method, rate, and amount;h. On scene weather observations.404. The Secretary of the PRDNR or his representative will immediately notify the Puerto RicoScientific Advisory Committee. The Scientific Advisory Committee will evaluate the environmentalimpact of the use of the dispersant or chemical agent with respect to the minimization of impact onenvironmentally sensitive area, economically important areas, beaches, or other areas of interest.405. The USCG, USEPA, USDOI, USDOC and the PRDNR further agree the OSC has pre-approval
to order the use of dispersants or chemical agents, subject to the following conditions:405.1 The use of dispersants or chemical agents is authorized only after all methods of physicalor mechanical removal are judged by the OSC to be infeasible.405.2 The pre-designated authority to use dispersants or chemical agents on oil discharges inaccordance with this Agreement is vested solely in the individual who is the predesignatedUSCG OSC. This authority will not be delegated.405.3 The decision to use dispersants or chemical agents shall be made only after consulting thePuerto Rico Coastal Atlas for Sensitivity of Coastal Environments and Wildlife to SpilledOil and the decision guidelines for dispersant use detailed in Subpart J of the Region IIRegional Contingency Plan (Part 2600 of the USCG Local Contingency Plan).405.4 Dispersants or chemical agents will be used only when they are expected to prevent orminimize substantial threat to public health or welfare, or serious environmental damage.405.5 Dispersants or chemical-agents may be used only in open waters that are at least 0.5nautical miles from any shoreline and where the water depth is greater than 60 feet deep.405.6 Dispersants or chemical agents shall not be used in, on, or over waters containing reefs;waters designated as marine reserves; mangrove areas; or waters in coastal wetlands;except with the prior and express concurrence of the PRDNR and USEPA, inconsultation with USDOC and USDOI. Coastal wetlands include:1) Submerged algal beds (rocky or unconsolidated bottom);2) Submerged seagrass beds; and3) Coral reefs405.7 Dispersants or chemical agents shall not be used in fresh or brackish waters.405.8 As a general rule,, if a discharge is too small to be removed by alternative mechanicalmethods, it is too small to consider the application of dispersants or chemical agents.405.9 Sinking agents are not dispersants and shall not be considered as authorized chemicalagents. Use of sinking agents is expressly prohibited by this Agreement and the NationalContingency Plan.405.10 If an oil discharge poses an imminent threat to a sensitive area restricted by protocol405.5, the USCG OSC must contact USEPA and PRDNR for concurrence, and consultwith USDOC and USDOI. If USEPA and PRDNR disagree, the opinion of PRDNR shallprevail. If PRDNR provides no answer within 4 hours, USEPA's decision will prevail. Inthe event that neither PRDNR nor USEPA can provide an answer within 4 hours, theUSCG OSC may proceed with the dispersant or chemical agent application if the threatrepresents a substantial threat to public health or welfare, or serious environmentaldamage is imminent if dispersants or chemical agents are not used.405.11 Any use of dispersants or chemical agents requires that a post incident debriefing takeplace within 45 days after the first application of dispersants or chemical agents.
