 AGENCY: Coast Guard, DHS.
 ACTION: Notice of proposed rulemaking.
 SUMMARY: The Coast Guard proposes to revise its pollution prevention equipment regulations to make them consistent with new International Maritime Organization (IMO) guidelines and specifications issued under the International Convention for the Prevention of Pollution from Ships (MARPOL) Annex I. These revisions should effectively implement MARPOL Annex I regulations, reduce the amount of oil discharged from vessels, and eliminate the use of ozone-depleting solvents in equipment tests. The proposed rule would require newly constructed vessels carrying oil in bulk to install cargo monitors that meet revised standards and require all vessels replacing or installing oil separators and bilge alarms to install equipment that meets revised standards. Tests for approval of this equipment would also be revised both to deal with common bilge contaminants and to eliminate the use of ozone-depleting solvents.

                        . Background and Purpose Under the Act to Prevent Pollution from Ships, Pub. L. 96-478, sections 2 and 4, 94 Stat. 2297, 2298 (Oct. 21, 1980), 33 U.S.C. 1901 and 1903, the Secretary of the Department in which the Coast Guard is operating is authorized to prescribe any necessary or desired regulations to carry out the provisions of the Act and of Annexes I and II of the International Convention 
                        ( print page 67067)
                        for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 relating to that Convention (MARPOL 73/78). Under the Act of August 26, 1983, Pub. L. 98-89, 97 Stat. 500, 504, 522, subtitle II of title 46 of the U.S. Code, specifically 46 U.S.C. 3703, the Secretary in which the Coast Guard is operating is authorized to issue equipment regulations for vessels carrying liquid bulk dangerous cargo, including oil. Authority under both of these acts has been delegated to the Coast Guard under Department of Homeland Security Delegation No. 0170.1 (2)(77) and (92)(b). For some time, it has been well understood by the international maritime community that existing pollution prevention equipment (PPE) is not adequately designed to process bilge wastes. Pollution prevention equipment on vessels encounter bilge wastes that are not replicated in test fluids used for certifying and approving PPE. This has led to release of more oil into the marine environment than desired. Of specific concern has been emulsified oil in water, surfactants (for example, detergents), and other contaminants typically found in bilge water. A second problem concerned the method by which oil content is measured in effluent samples during the approval process. Existing methods require the use of ozone-depleting solvents, specifically carbon tetrachloride and Freon 113 (CFC 113). Both an international treaty and laws of the United States call for phasing out the use of these solvents. Therefore, an alternative test method was desired. Having identified these concerns, the International Maritime Organization's (IMO) Marine Environment Protection Committee (MEPC) instructed the Ship Design and Equipment subcommittee to develop new performance standards to replace those referenced in MARPOL Annex I. The Ship Design and Equipment subcommittee drafted new resolutions, in which the U.S. participated, that were ultimately approved by the MEPC at its 49th session in July 2003 and designated as MEPC.107(49) and MEPC.108(49). Which Vessels Would This Proposed Rule Affect? Our proposed rule would not change the type or class of vessels that require a cargo monitor, oily-water separator (OWS), or bilge alarm under 33 CFR part 155, subpart B, or 33 CFR part 157; it would only require that such equipment meet new pollution prevention standards. Regulatory History Even before Annex I of MARPOL 73/78 came into force internationally in 1983, the Coast Guard issued a final rule (44 FR 53352, September 13, 1979) containing PPE design and approval requirements. On December 31, 2003, the Coast Guard published in the 
                        **Federal Register**
                         (68 FR 75603) a notice of policy informing the public of the new MEPC resolutions, our desire to update 46 CFR subpart 162.050, and our willingness to consider alternatives to the performance and testing standards in part 162.050. Discussion of Proposed Rule The proposed rule would revise 46 CFR subpart 162.050 to reflect the new IMO PPE guidelines and specifications that governments have been invited to apply on or after January 1, 2005, to their implementation of MARPOL Annex I regulations. The proposed rule would also align 46 CFR subpart 162.050 more closely with the IMO PPE guidelines by removing the bilge monitor standard. The six factors that were considered in the decision to propose to remove the bilge monitor follow: 1. A bilge monitor includes a 100 parts per million (ppm) performance standard that is no longer an allowed discharge concentration of oil at sea nationally or internationally. 2. There is no longer an equivalent to a bilge monitor requirement in the IMO guidelines or MARPOL Annex I. The IMO resolutions and Annex I call for three types of PPE equipment: cargo monitors, oil separators and bilge alarms. In addition to these three types of equipment, the equipment that can obtain approval under subpart 162.050 currently also includes bilge monitors. Retaining the bilge monitor design and approval standards in the proposed subpart 162.050 results in unique testing and performance requirements inconsistent with international standards. 3. According to our records, the Coast Guard has not received an approval application for a bilge monitor in more than a decade. 4. Only four bilge monitors are listed in the Coast Guard equipment database and only one of those has maintained an “approved” status. All the others are “former-may use” or “expired.” 5. There are no specific requirements in the current regulations for installing a bilge monitor—it is an alternative to installation of a bilge alarm. 6. The new bilge alarm requirements incorporate a recording function which, other than the 100-ppm alarm, was the major difference between the bilge alarm and bilge monitor. As proposed, a bilge monitor requirement in the proposed subpart 162.050 would be both redundant and obsolete. Unlike many of the engineering references incorporated into our current regulations, subpart 162.050 contains text taken in large part from the IMO documents detailing the performance and testing requirements. Two options exist for updating subpart 162.050: 1. Replace existing regulatory text with detailed text implementing the new IMO standards by describing them; or 2. Replace existing regulatory text with new text that relies heavily on incorporating the new standards by reference to resolutions MEPC.107(49) and MEPC.108(49), and ISO 9377-2. In seeking to avoid conflicts between Coast Guard PPE regulations and MARPOL Annex I guidelines and specifications that Member States are invited to make applicable on or after January 1, 2005, we considered incorporating the MARPOL guidelines and specifications by reference—and not have any differences between the MARPOL guidelines and specifications and Coast Guard PPE standards—but we decided to maintain some differences. Some of our regulations will be more specific and concrete than the MARPOL Annex I guidelines and specifications. We will, for example, specify when and where inclination tests will be performed. These differences are intended to make the regulations easier to enforce and more likely to ensure that the oil-release-reduction goals of the MARPOL Annex I guidelines and specifications are met.

Regulatory Evaluation This proposed rule is not a “significant regulatory action” under section 3(f) of Executive Order 12866, Regulatory Planning and Review, and does not require an assessment of potential costs and benefits under 
                        ( print page 67068)
                        section 6(a)(3) of that Order. The Office of Management and Budget has not reviewed it under that Order. A draft Regulatory Evaluation follows: Background This NPRM proposes to change the performance standards of oily-water separators (OWS), bilge alarms, and cargo monitors to meet the revised guidelines and specifications for the MARPOL Annex I standards. In analyzing the cost impact of this proposed rule, we considered the increase in cost to buyers of new vessels who must install new pollution prevention equipment meeting the revised standards, and owners and operators of existing vessels who must replace old equipment with the new pollution prevention equipment. Proposed Action The Coast Guard proposes to make the following changes to pollution prevention equipment performance standards, outlined in 46 CFR part 162, subpart 162.050: Remove the requirement for a bilge monitor;
                    Require OWSs to effectively process emulsified oils, surfactants, and contaminants;
                    Change standards for the bilge alarm which must now: 1. Pass new tests using emulsified oil and contaminants; 2. have a ppm display; 3. display each change in oil content of the mixture it is measuring within 5 seconds after the change occurs instead of every 20 seconds; 4. limit access to the bilge alarm beyond checking instrument drift must be limited; repeatability of the instrument reading and the ability to re-zero the instrument must require the breaking of a seal; 5. activate its alarm whenever clean water is used for cleaning or zeroing purposes; and 6. record date, time, alarm status, and operating status of the 15 ppm bilge separator. The recording device must also store data for at least 18 months and be able to display or print a protocol. In the event the 15 ppm bilge alarm is replaced, means must be provided to ensure the data recorded remains available on board for 18 months; and,
                    Change standards for cargo monitors that are used with category C and D oil-like noxious liquid substances. Based on our research, we found that the manufacturers of cargo monitors, plan to sell these monitors meeting the new standards for approximately the same retail price as the old equipment. Therefore, there is no additional cost to vessel owners for this requirement. We expect there to be no additional cost to industry for removing the requirement for bilge monitors, or changing standards for cargo monitors because there will be no change in cost for installation, operation, and maintenance. Applicability This proposed rule applies to all ocean-going vessels that operate in U.S. waters. Foreign vessels in compliance with MARPOL need not prove compliance with the domestic equipment approval standards. Therefore, this rule primarily affects U.S. flag vessels. The vessels impacted by the proposed changes for the bilge alarm and the OWS are described in 33 CFR 155.380, and are divided into three main categories: 33 CFR 155.350—Oceangoing vessels of less than 400 gross tons (GT). These vessels are not required to have the equipment on board if they have the capacity to retain on board all oily mixtures and can discharge these oily mixtures to a reception facility. Certain vessels, in this category that embark on international voyages, however, are required to have an International Pollution Prevention Certificate (IOPP) that requires them to have pollution prevention equipment on board. Based on Coast Guard data, we estimate that 30 percent of the fleet have the IOPP Certificate and have OWSs and bilge alarms on board.
                    Oceangoing vessels of 400 GT and above, but less than 10,000 GT. The current regulations require all vessels in this category to have an installed OWS and if the vessel ballasts the fuel tanks and/or plans to discharge through the OWS within 12 nm of land the vessel must also have a bilge alarm. Additionally, vessels in this category that embark on international voyages, which are required to have an IOPP Certificate, have the pollution prevention equipment on board. Based on Coast Guard and industry information, we assume the majority of new construction oceangoing vessels have bilge alarms and the OWSs on board.
                    33 CFR 155.370—Oceangoing vessels of 10,000 GT and above. The current regulation requires all oceangoing vessels in this tonnage range to have both an OWS and bilge alarm. We assume all of these vessels comply with these regulations and have the equipment. Costs The following vessel population estimates are based on 2004 Coast Guard data. There are approximately 86 new oceangoing vessels built per year that would be affected by this proposed rule. Of these, approximately 29 new vessels are 400 GT or greater and must meet the new requirements to have bilge alarms and oily water separators that meet the new standards. Of the remaining 57 vessels less than 400 GT, we assume 30 percent, or approximately 17 vessels, will be installing the equipment because they will embarking on international voyages and are required to carry pollution prevention equipment. All existing vessels subject to these PPE regulations, approximately 5,838 U.S. flag vessels, must install equipment that meets the new standards whenever the owners or operators replace the equipment. Based on Coast Guard data, we assume that the entire existing fleet of vessels 400 GT and over will update its equipment as it breaks down over the next 20 years, which is approximately the length of service for these U.S. flag vessels. We assume that the 30 percent of the fleet below 400 GT that has this equipment on board will also update it once over the service life of the vessel. The cost of this proposed rule to vessel owners is the additional price owners must pay for the higher-priced pollution prevention equipment that meets the new MARPOL standards. The owners and operators of existing vessels would face no immediate mandatory implementation costs from this proposed rule, but they would face ongoing costs as they update equipment or install new equipment on new vessels. We calculated the cost of the rulemaking for the next 10 years (2005-2014), which is a long enough period of analysis to capture the majority of the future costs of this rulemaking. This follows OMB's guidance that the ending point for calculating costs “should be far enough in the future to encompass all significant benefits and costs likely to result from the rule” (see OMB Circular A-4, page 31). However, in other cases, simply presenting annualized costs are sufficient. For example, OMB's Circular A-4 (page 36) notes that if the expected flow of costs is constant over time, then annualizing the cost stream is sufficient and further discounting is unnecessary. That said, for this rulemaking we would have been on safe ground simply reporting annualized costs. For vessel owners and operators that would be replacing equipment once over the service life of the vessel or once every twenty years, we assume that five percent of the affected population would update their equipment for each year in the 10-year period of analysis. 
                        ( print page 67069) We considered possible increases in the operation and maintenance (O&M) costs. Based on Coast Guard and industry information, we estimate that the O&M cost of the new equipment would not be more than the O&M costs of the existing equipment, and in some instances would cost less. Therefore, we assume that there would be no significant increases in O&M costs, since vessels routinely face similar costs for existing installed equipment. For OWSs, there is a wide range in the price of the equipment depending on flow rates and levels of technological capability. Based on discussions with manufacturers, we find that there is currently considerable variability in market prices as suppliers begin to market and sell the new equipment. Still, we believe we have estimated average price increases that are reasonably accurate. We separated the vessel categories into the three groups discussed earlier, and assume an average price increase of: $8,000 for vessels below 400 GT;
                    $12,000 for vessels 400 GT or more and less than 10,000 GT; and
                    $18,000 for vessels 10,000 GT and over. For bilge alarms, there is less of a variation in the price. The change in the price ranges from approximately $400 to $1,500 and we assume an average price increase of $1,000 for all vessel categories. Thus, the total price increase for both oily water separators and bilge alarms combined is: $9,000 for vessels below 400 GT;
                    $13,000 for vessels 400 GT or more and less than 10,000 GT; and
                    $19,000 for vessels 10,000 GT and over. We estimate the total annual cost for new vessels is $548,000 and the total annual cost for existing vessels is $2,298,000. See Tables 1 and 2 below for details on the calculations of the annual costs. Table 1.—Annual Cost of Oily-Water Separators (OWS) & Bilge Alarms For New Vessels

 We estimate the total annual cost of this rule to industry would be $2,846,000 ($548,000 + $2,298,000). The present value of the total cost for the next 10 years is $21,388,531, based on a 7 percent discount rate, and $25,005,266, based on a 3 percent discount rate. To the extent that shippers purchase equipment from U.S. suppliers, this is a transfer from shippers to suppliers. To the extent that shippers will pass on these costs to their customers, these consumers and their customers will bear most of the burden of the rule. Given that vessel owners will phase in the equipment over 20 years, vessel owners may be more likely to try to absorb as much of this increase as possible over the first few years. To the extent that vessel owners do eventually pass on costs to consumers, these price increases would be small given vessel owners and operators can spread these costs over thousands of voyages. Benefits The benefits of this proposed rule are mainly in the improved environmental conditions resulting from the use of PPE which meets higher standards of pollution prevention. The new OWSs will better handle the separation of emulsified oils, surfactants and contaminants from water whereas in previously approved units this may not have occurred. There would also be a broader range and volume of pollutants no longer released into the environment because of these new standards, which is a positive impact of this proposed rule. Testing standards for pollution prevention equipment outlined in 46 CFR 162.050-39 currently require the use of the solvents carbon tetrachloride and Freon 113 (CFC 113), which have been phased out by the Montreal Protocol on Substances that Deplete the Ozone Layer. This proposed rule would require a new test protocol to be used for testing the oil separating capabilities of pollution prevention equipment—outlined in 46 CFR 162.050-39—that does not include these substances. Small Entities Under the Regulatory Flexibility Act (5 U.S.C. 601-612), we have considered whether this proposed rule would have a significant economic impact on a substantial number of small entities. The term “small entities” comprises small businesses, not-for-profit organizations that are independently owned and operated and are not dominant in their fields, and governmental jurisdictions with populations of less than 50,000. The small entities affected by the proposed rule are vessels owners required to install or replace pollution prevention equipment meeting the new standards on their vessels. To analyze the financial impact of the proposed rule on small entities, we selected and analyzed a random sample of 360 vessels that is statistically representative of the target population 
                        ( print page 67070)
                        of 5,838. In the entire population, 2,780 companies own these 5,838 vessels. In the random sample, we found that 263 companies owned the 360 vessels. In this sample, 69 small companies owned 79 vessels, 47 large companies owned 99 vessels, the Federal government owned 26 vessels and we found 156 vessels with no revenue information available on their 146 owners. We then assessed the impact of cost on the revenue of the companies with information that we identified as small entities, and broke them down by the percentage impact on revenue. The large majority of small entities (about 87 percent) face an impact on revenue between 0 and 4 percent. To be conservative, we assumed that all vessels with no available information on their ownership were owned by small entities. We further assumed that the percentage impact of annual cost on annual revenue was distributed in the same proportion as the small businesses for both the vessels with no information in the random sample, and for the entire target population. See Table 3 below for details. Table 3.—Impact of Cost on Small Entities

 Under the Clean Air Act, as amended, specifically under 42 U.S.C. 7671a, we must eliminate the use of ozone-depleting testing solvents in our current PPE regulations. Therefore, “no action” is not an option. Also, the United States is party to MARPOL Annex I. To effectively implement MARPOL Annex I regulations, we must revise our other PPE regulations to reflect that resolutions MEPC.107(49) and MEPC.108(49) have superseded resolutions MEPC.60(33) and A.586(14), respectively. We believe the proposed regulations will have a minimal costs to small businesses. First, existing vessels are not required to immediately install pollution prevention equipment meeting the new standards, but only when they are replacing it, which could be over a long period of time. Second, 57 percent of vessel types in the small business category are below 400 GT, and owners of these vessels have the option of not installing pollution prevention equipment and instead discharging oily mixtures at a reception facility. Finally, the prices of OWS systems (the highest cost component of this proposed rule) vary widely depending on a range of factors including their technological capability, so that vessel owners can choose cheaper versions within the options available to them. Therefore, the Coast Guard certifies under 5 U.S.C. 605(b) that this proposed rule would not have a significant economic impact on a substantial number of small entities. If you think that your business, organization, or governmental jurisdiction qualifies as a small entity and that this rule would have a significant economic impact on it, please submit a comment to the Docket Management Facility at the address under 
                        **ADDRESSES.**
                         In your comment, explain why you think it qualifies and how and to what degree this rule would economically affect it. Assistance for Small Entities Under section 213(a) of the Small Business Regulatory Enforcement Fairness Act of 1996 (Pub. L. 104-121), we want to assist small entities in understanding this proposed rule so that they can better evaluate its effects on them and participate in the rulemaking. If the rule would affect your small business, organization, or governmental jurisdiction and you have questions concerning its provisions or options for compliance, please consult Lt. George Grills, Office of Systems Engineering (G-MSE-3), Coast Guard, telephone 202-267-6640. The Coast Guard will not retaliate against small entities that question or complain about this rule or any policy or action of the Coast Guard. Collection of Information This proposed rule would call for no new collection of information under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520). The paperwork burden associated with the manufacture, laboratory testing, approval tests, and marking of pollution prevention equipment is addressed in the existing collection of information, OMB #1625-0035, entitled “Title 46 CFR Subchapter Q: Lifesaving, Electrical, and Engineering Equipment; Construction and Materials.” This collection of information was approved by the Office of Management and Budget on December 10, 2002, and will expire after the 3-year approval period ends on December 31, 2005. Federalism A rule has implications for federalism under Executive Order 13132, Federalism, if it has a substantial direct effect on State or local governments or would either preempt State law or impose a substantial direct cost of compliance on them. Based on our survey of vessels expected to be effected, we have identified only 26 state-owned vessels that may be affected, and these vessels are already subject to regulation under the sections affected by the proposed amendments. Therefore, we conclude the proposed rule would not impose a substantial direct cost of compliance on State or local governments. It is well settled that States may not regulate in categories reserved for regulation by the Coast Guard. It is also well settled, now, that all of the categories covered in 46 U.S.C. 3306, 3703, 7101, and 8101 (design, construction, alteration, repair, maintenance, operation, equipping, personnel qualification, and manning of vessels), as well as the reporting of casualties and any other category in which Congress intended the Coast Guard to be the sole source of a vessel's obligations, are within the field 
                        ( print page 67071)
                        foreclosed from regulation by the States. (See the decision of the Supreme Court in the consolidated cases of 
                        *United States*
                         v. 
                        *Locke*
                         and

                         v. 
                        *Locke,*
                         529 U.S. 89, 120 S. Ct. 1135 (March 6, 2000)). Our proposed rule would revise standards for pollution prevention equipment. Because the States may not regulate within this category, preemption under Executive Order 13132 is not an issue. Unfunded Mandates Reform Act The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538) requires Federal agencies to assess the effects of their discretionary regulatory actions. In particular, the Act addresses actions that may result in the expenditure by a State, local, or tribal government, in the aggregate, or by the private sector of $100,000,000 or more in any one year. Though this proposed rule would not result in such an expenditure, we do discuss the effects of this rule elsewhere in this preamble. Taking of Private Property This proposed rule would not effect a taking of private property or otherwise have taking implications under Executive Order 12630, Governmental Actions and Interference with Constitutionally Protected Property Rights. Civil Justice Reform This proposed rule meets applicable standards in sections 3(a) and 3(b)(2) of Executive Order 12988, Civil Justice Reform, to minimize litigation, eliminate ambiguity, and reduce burden. Protection of Children We have analyzed this proposed rule under Executive Order 13045, Protection of Children from Environmental Health Risks and Safety Risks. This rule is not an economically significant rule and would not create an environmental risk to health or risk to safety that might disproportionately affect children. Indian Tribal Governments This proposed rule does not have tribal implications under Executive Order 13175, Consultation and Coordination with Indian Tribal Governments, because it would not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes. Energy Effects We have analyzed this proposed rule under Executive Order 13211, Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use. We have determined that it is not a “significant energy action” under that order because it is not a “significant regulatory action” under Executive Order 12866 and is not likely to have a significant adverse effect on the supply, distribution, or use of energy. The Administrator of the Office of Information and Regulatory Affairs has not designated it as a significant energy action. Therefore, it does not require a Statement of Energy Effects under Executive Order 13211. Technical Standards The National Technology Transfer and Advancement Act (NTTAA) (15 U.S.C. 272 note) directs agencies to use voluntary consensus standards in their regulatory activities unless the agency provides Congress, through the Office of Management and Budget, with an explanation of why using these standards would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (
                        *e.g.*, specifications of materials, performance, design, or operation; test methods; sampling procedures; and related management systems practices) that are developed or adopted by voluntary consensus standards bodies. This proposed rule uses the following new voluntary consensus standards: 1. IMO Assembly Resolution A.393(X)—Recommendation on International Performance and Test Specifications For Oily-Water Separating Equipment and Oil Content Meters; 2. IMO Assembly Resolution A.496(XII)—Guidelines and Specifications for Oil Discharge Monitoring and Control Systems for Oil Tankers; 3. IMO Assembly Resolution A.586(14)—Revised Guidelines and Specifications for Oil Discharge Monitoring and Control Systems for Oil Tankers; 4. IMO Marine Environment Protection Committee Resolution MEPC.13(19)—Guidelines for Plan Approval and Installation Survey of Oil Discharge Monitoring and Control Systems for Oil Tankers and Environmental Testing of Control Sections Thereof; 5. IMO Marine Environment Protection Committee Resolution MEPC.108(49)—Revised Guidelines and Specifications for Oil Discharge Monitoring and Control Systems for Oil Tankers; 6. International Organization of Standardization Standard ISO 8217 (1996) Petroleum products—Fuels (class F)—Specification of marine fuels; 7. International Organization of Standardization Standard ISO 9377-2 (2000), Water Quality—Determination of hydrocarbon oil index—Part 2: Method Using solvent extraction and Gas Chromatography. The proposed sections that reference these standards and the locations where these standards are available are listed in 33 CFR 157.02 and 46 CFR 162.050-4. Environment We have analyzed this proposed rule under Commandant Instruction M16475.lD, which guides the Coast Guard in complying with the National Environmental Policy Act of 1969 (NEPA) (42 U.S.C. 4321-4370f), and have concluded that there are no factors in this case that would limit the use of a categorical exclusion under section 2.B.2 of the Instruction. Therefore, this rule is categorically excluded, under figure 2-1, paragraph (34)(e), of the Instruction, from further environmental documentation. These regulations concern equipment approval and carriage requirements. A preliminary “Environmental Analysis Check List” is available in the docket where indicated under the “Public Participation and Request for Comments” section of this preamble. Comments on this section will be considered before we make the final decision on whether this rule should be categorically excluded from further environmental review.

 § 157.12b
  Oil discharge monitoring and control systems must be fitted to oil tankers to which this subpart applies. A monitoring and control system must employ a control unit and be fitted with a starting interlock and overboard discharge control.
 § 157.12c
  (a) The oil discharge monitoring and control system must be designed to 
                                ( print page 67073)
                                ensure that user access is restricted to essential controls. Access beyond these controls must be available for emergency maintenance and temporary repair but must require the breaking of security seals or activation of another device which indicates an entry to the equipment. (b) The seals must be of a design that only the manufacturer or the manufacturer's agent can replace the seals or reset the system following inspection and permanent repairs to the equipment. (c) The accuracy of the monitoring system must be verified during International Oil Pollution Prevention certificate renewal surveys. The calibration certificate certifying date of last calibration check must be retained on board for inspection purposes. (d) The monitoring system may have several scales as appropriate for its intended use. The recording device fitted to a meter which has more than one scale must indicate the scale which is in use. (e) Simple means must be provided aboard ship to check on instrument drift must be limited; repeatability of the instrument reading, and the ability to re-zero the instrument. (f) Ship staff training must include familiarization in the operation and the maintenance of the equipment. (g) The routine maintenance of the monitoring system and troubleshooting procedures must be clearly defined in the Operating and Maintenance Manual. All routine maintenance and repairs must be recorded.
 § 157.12d
  (a) 
                                *Oil discharge monitoring and control system.*
                                 (1) The monitoring system must be capable of effectively monitoring and controlling the discharge of any effluent into the sea through those overboard discharge outlets permitted by § 157.11 that are necessary to fulfill the operational requirements of the oil tanker. (2) The discharge of dirty ballast water or other oil-contaminated water from the cargo tank areas into the sea through outlets which are not controlled by the monitoring system is prohibited. (3) The monitoring system must function effectively under all environmental conditions that oil tankers normally encounter, and must be designed and constructed to satisfy the specifications for approval in 46 CFR subpart 162.050. Moreover— (i) The system must be designed so that no discharge of dirty ballast or other oil-contaminated water from the cargo tank areas can take place unless the monitoring system is in the normal operating mode and the relevant sampling point has been selected; (ii) Preferably the system should sample the effluent discharge from a minimum number of discharge outlets and be arranged so that discharge overboard can take place via only one outlet at a time; (iii) Where it is intended that more than one line be used for simultaneous discharging purposes, one cargo monitor, together with a flow meter, must be installed in each discharge line. These instruments must be connected to a common processor; and (iv) To avoid alarms because of short-term high oil concentration signals (spikes) causing indications of high instantaneous rates of discharge, the short-term high ppm signal may be suppressed for a maximum of 10 seconds. Alternatively, the instantaneous rate of discharge may be continuously averaged during the preceding 20 seconds or less as computed from instantaneous ppm values of the cargo monitor readings received at intervals not exceeding 5 seconds. (4) The monitoring system must comprise— (i) A cargo monitor to measure the oil content of the effluent in ppm. The monitor must be approved in accordance with the provisions contained in 46 CFR 162.050 and be certified to take into account the range of cargoes carried; (ii) A flow rate indicating system to measure the rate of effluent being discharged into the sea; (iii) A ship speed indicating device to give the ship's speed in knots; (iv) A ship position indicating device to give the ship's position—latitude and longitude; (v) A sampling system to convey a representative sample of the effluent to the cargo monitor; (vi) An overboard discharge control to stop the overboard discharge; (vii) A starting interlock to prevent the discharge overboard of any effluent unless the monitoring system is fully operational; and (viii) A control section comprising— (A) A processor that accepts signals of oil content in the effluent, the effluent flow rate and the ship's speed, and computes these values into liters of oil discharged per nautical mile and the total quantity of oil discharged; (B) A means to provide alarms and command signals to the overboard discharge control; (C) A recording device to provide a record of data required under § 157.12d(h)(2); (D) A data display to exhibit the current operational data required under § 157.12d(i); (E) A manual override system to be used in the event of failure of the monitoring system; and (F) A means to provide signals to the starting interlock to prevent the discharge of any effluent before the monitoring system is fully operational. (5) Each main component of the monitoring system must be fitted with a name-plate, properly identifying the component by assembly drawing number, type or model number and serial number, as appropriate. (6) The electrical components of the monitoring system that are to be installed in an explosive atmosphere must be in compliance with 46 CFR 162.050-25. (b) 
                                *Sampling system.*
                                 (1) Sampling points must be located so that relevant samples can be obtained from those outlets that are used for operational discharges in accordance with paragraph (a) of this section. The sampling probes located in the overboard discharge lines and the piping system connecting the sampling probes to the cargo monitor must meet the requirements of this paragraph. (2) The piping and probes must be of a material resistant to fire, corrosion, and oil and be of adequate strength, and properly jointed and supported. (3) The system must have a stop-valve fitted adjacent to each probe, except that, where the probe is mounted in a cargo line, two stop-valves must be fitted, in series, in the sample line; one of these may be the remote controlled sample selector valve. (4) Sampling probes must be arranged for easy withdrawal and must, as far as practicable, be mounted at an accessible location in a vertical section of the discharge line. Should it be necessary to fit sampling probes in a horizontal section of the discharge line it must be ascertained, during the installation survey, that the pipe runs full of liquid at all times during the discharge of the effluent. Sampling probes must normally penetrate inside the discharge pipe to a distance of one quarter the diameter of that pipe. (5) Means must be provided for cleaning the probes and piping system by the provision of permanent clean water flushing arrangements or an equivalent method. The design of the probes and piping must be such as to minimize their clogging by oil, oily residue, and other matter. (6) The velocity of the fluid in the piping must be such that, taking into consideration the length of the piping, the overall response time must be as 
                                ( print page 67074)
                                short as possible between an alteration in the mixture being pumped and the alteration in the cargo monitor reading and in any case not more than 40 seconds, including the response time of the cargo monitor. (7) The location of sampling probes in relation to any point of flow diversion to a slop tank must be selected with regard to the need for sampling the oily water in the recirculation mode. (8) The arrangements for driving the sampling pump or any other pumps used in the system must account for the safety requirements of the space in which the pump is located. Any bulkhead penetration between a hazardous and a non-hazardous area must be of a design meeting the requirements of 46 CFR 32.60-20 and 46 CFR subpart 111.105. (9) The flushing arrangement must be such that where necessary it can be utilized for test-running and stabilizing the cargo monitor and correcting for zero setting. (10) Sample water returning to the slop tank must not be allowed to free-fall into the tank. In tankers equipped with an inert gas system, a water seal meeting the requirements of 46 CFR 32.53-10(b) must be arranged in the piping leading to a slop tank. (11) A valve must be provided for the manual collection of samples from the inlet piping to the cargo monitor at a point downstream of any sampling pump. (c) 
                                *Flow rate indicating system.*
                                 (1) A flow meter for measuring the rate of discharge must be installed in a vertical section of a discharge line or in any other section of a discharge line as appropriate, so as to be always filled with the liquid being discharged. (2) A flow meter must employ an operating principle which is suitable for shipboard use and, where relevant, can be used in large diameter pipes. (3) A flow meter must be suitable for the full range of flow rates that may be encountered during normal operation. Alternatively, arrangements such as the use of two flow meters of different ranges or a restriction of the operational flow rate range may be employed if necessary to meet this requirement. (4) The flow meter, as installed, must have an accuracy of ±10 percent, or better, of the instantaneous rate of discharge throughout the operating range for discharging the effluent. (5) Any component part of the flow meter in contact with the effluent should be of corrosion-resistant and oil-resistant material of adequate strength. (6) The design of the flow metering arrangements must account for the safety requirements of the space in which such metering arrangements are located. (d) 
                                *Ship's speed indicating system.*
                                 The automatic speed signal required for a monitoring system must be obtained from the ship's speed indicating device by means of a repeater signal. The speed information used may be either speed over the ground or speed through the water, depending upon the speed measuring equipment installed on board. Note to paragraph (d): See “Recommendation on Performance Standards for Devices to Indicate Speed and Distance,” Annex to resolution A.824(19) as amended by resolution MSC.96(72). (e) 
                                *Ship position indicating device.*
                                 The ship position indicating device must consist of a receiver for a global navigation satellite system or a terrestrial radio navigation system, or other means, suitable for use at all times throughout the intended voyage to establish and update the ship's position by automatic means. (f) 
                                *Overboard discharge control management.*
                                 The overboard discharge control must be able to stop the discharge of the effluent into the sea automatically by either closing all relevant overboard discharge valves or stopping all relevant pumps. The discharge control arrangement must be fail-safe so that all effluent discharge is stopped when the monitoring system is not in operation, at alarm conditions, or when the monitoring system fails to function. (g) 
                                *Processor and transmitting device.*
                                 (1) The processor of a control section must receive signals from the cargo monitor, the flow rate indicating system and the ship's speed indicating system at time intervals not exceeding 5 seconds and must automatically compute the following: (i) Instantaneous rate of discharge of oil in liters per nautical mile; and (ii) Total quantity of oil discharged during the voyage in cubic meters or liters. (2) When the limits imposed by § 157.37(a)(3) and (4) are exceeded, the processor must provide alarms and provide command signals to the overboard discharge control arrangement which will cause the discharge of effluent into the sea to stop.

  (a) * * * (4) The influent water used in each test must be clean fresh water or clean fresh water in solution with sodium chloride. In either case, the relative density of the water must be no greater than 1.015 at 20 °C. 
 (b) The following tests must be conducted using Test Fluid A: (1) 
                                *Test No. 1A.*
                                 The separator is filled with water and started. It is first fed with pure Test Fluid A for at least 5 minutes and then with a mixture of Test Fluid A and water influent containing Fluid A content of between 5,000 and 10,000 ppm until a steady flow rate occurs. After the flow rate is steady, the influent is fed to the separator for 30 minutes. Samples of separated water effluent are taken after the first 10 and 20 minutes. At the end of the 30-minute period, the air cock on the test rig is opened and, if necessary, the oil and water supply valves are closed to stop the flow of influent. A sample is then taken of the separated water effluent as the effluent flow ceases. (2) 
                                *Test No. 2A.*
                                 Repeat Test No. 1A in paragraph (b)(1) of this section using an influent containing approximately 25 percent oil and 75 percent water. Percentage is on a by volume basis. (3)

                                 The separator is fed with 100 percent Test Fluid A until Fluid A is discharged at the oil discharge outlet of the separator at essentially the same rate that oil is being fed to the separator. The separator is then fed with 100 percent Test Fluid A for 5 additional minutes. If any oily mixture is discharged from the separated water outlet on the separator during the test, that observation is recorded. (4) 
                                *Test No. 4A.*
                                 The separator is fed with water for 15 minutes. Samples of the separated water effluent are taken at the beginning of the test and after the first 10 minutes. (5) 
                                *Test No. 5A.*
                                 The separator is operated automatically for 3 hours. During the test, the separator is continuously fed with an influent varying from water to a mixture of 25 percent Test Fluid A in water and back to water every 15 minutes. The Test Fluid A concentration in the influent is varied in at least five equal increments during each 15-minute period and the time intervals between the incremental changes are equal. During the last hour, the separator must be inclined at an angle of 22.5 ° with the plane of its normal operating position.

After the flow rate is steady, the influent containing the 6 percent Test Fluid C solution is fed to the separator operating automatically for 3 hours. Samples of separated water effluent are taken at 50 minutes and 100 minutes. At the end of the 3-hour period, the air cock on the test rig is opened and, if necessary, the oil and water supply valves are closed to stop the flow of influent. A sample is then taken of the separated water effluent as the effluent flow ceases. 21. In § 162.050-25— a.

After increasing the pressure or flow rate, the oil content in the mixture is increased until the alarm actuates. The ppm display is recorded and a sample of the mixture causing actuation is taken. (e) 
                                *Test No. 4A Shut-off Test.*
                                 (1) The steps described in paragraph (d)(1) of this section are repeated. (2) The metering and water pumps of the test rig are stopped for 8 hours with the bilge alarm left turned on with no other changes made. (3) The metering and water pumps are started and the Test Fluid B content of the mixture is increased until the bilge alarm actuates. A sample of the mixture causing actuation is taken. The bilge alarm ppm display readings before and after the 8-hour period will be recorded. (f) 
                                *Test No. 5A Supply Voltage Variation Test.*
                                 (1) The supply voltage to the bilge alarm is raised to 110 percent of its design supply voltage. The bilge alarm is fed with a mixture of Test Fluid B and water and the test fluid content of the mixture is increased until the bilge alarm actuates. The ppm display is recorded and a sample of the mixture causing actuation is taken. (2) The supply voltage to the alarm is lowered to 90 percent of its design supply voltage. The bilge alarm is fed with a mixture of Test Fluid B and water and the test fluid content of the mixture is increased until the bilge alarm actuates. The ppm display is recorded and a sample of the mixture causing actuation is taken. (3) Upon completion of the steps described in paragraph (f)(2) of this section, the supply voltage to the alarm is returned to its design value. (4) The steps described in paragraphs (f)(1) through (f)(3) of this section are repeated varying each other power supply to the alarm in the manner prescribed in those steps for supply voltage. (g) 
                                *Test No. 6A Calibration and Zero Test.*
                                 (1) The steps described in paragraph (b)(1) of this section are repeated and then the steps in paragraph (d)(1) of this section are repeated. (2) The bilge alarm is fed with a 15 ppm mixture of Test Fluid B and water for eight hours and any calibration drift is recorded. Samples of the mixture must be taken at the beginning of the test and at 2-hour intervals until the completion of the 8-hour period. (3) The steps in paragraph (g)(2) of this section are repeated using clean, oil-free water only. Any zero drift is recorded. (h) 
                                *Test No. 7A Response Time Test.*
                                 (1) The bilge alarm is fed with a 40 ppm mixture of Test Fluid B and water until the bilge alarm actuates. The time of turning on the metering pump of the test rig and the time of alarm actuation are recorded. The flow rate on the flow meter of the test rig is also recorded. (i) 
                                *Test No. 8A Shut Down and Re-start Test.*
                                 (1) All power to the bilge alarm is shut off for 1 week. After 1 week the alarm is then started, zeroed, and calibrated. (2) The steps described in paragraph (d)(1) of this section are repeated. Water is then fed to the monitor for 1 hour. (3) The steps described in paragraph (i)(2) of this section are repeated seven additional times. During the last hour, the alarm must be inclined at an angle of 22.5 ° with the plane of its normal operating position. 27. In § 162.050-37, in paragraph (b), remove the figure “4” and add, in its place, the word “2”; redesignate paragraphs (b)(1) through (3) as paragraphs (b)(1)(i) through (iii); redesignate paragraph (b) introductory text as (b)(1) and designate the undesignated paragraph as (b)(2); and add paragraph (c) to read as follows:
 § 162.050-37
  
 (c) After completion of the test described in paragraph (b) of this section, the test must be repeated and any significant change in the vibration pattern will be noted in the test report. 28. Revise § 162.050-39 to read as follows:
 § 162.050-39
  (a) The collection and testing of all samples of oil in water from the required test will be accomplished in accordance with ISO 9377-2 (2000), Water Quality—Determination of hydrocarbon oil index—Part 2: Method Using solvent extraction and Gas Chromatography (Incorporated by reference, see § 162.050-4). (b) Testing facilities may continue to use the infrared spectrophotometer assay in lieu of ISO 9377-2, so long as supplies of reagents necessary for the testing are available.
