ABSTRACT A summary is presented of a study conducted to characterize tar samples recovered from the marine environment. The samples were collected by the U.S. Coast Guard primarily from the northwestern Atlantic Ocean and along the eastern coast of the United States. A multiparameter analytical approach was applied which involved microscopy, chromatography, infrared, and other analytical methods. Patterns were recognized which allowed a classification of the samples into distinct groups and which suggested possible origins. Contract DOT-CG-23,379A, U.S. Coast Guard Headquarters, Washington, D.C. A complete report of the investigation covered under this contract (DOT-CG-23,379A) is available through the National Technical Information Service, Springfield, Va. 22151.

ABSTRACT The Agreement of Cooperation Between the United States of America and the United Mexican States Regarding Pollution of the Marine Environment by Discharges of Hydrocarbons and other Hazardous Substances, signed in Mexico City in 1980, provides a framework for cooperation in response to pollution incidents that pose a threat to the waters of both countries. Under this agreement, MEXUSPAC organizes Mexican and U.S. response agencies to plan for and respond to pollution emergencies in the marine environment. The MEXUSPAC contingency plan designates the commandant of the Mexican Second Naval Zone and the chief of the U.S. Coast Guard 11th District Marine Safety Division as the MEXUSPAC Cochairmen, and defines on-scene commanders, joint operations centers, and communications protocols that would be needed to coordinate the response to pollution incidents affecting both countries.

ABSTRACT The annual volume of oil spilled into the marine environment by tank vessels (tank barges and tanks hips) is analyzed against the total annual volume of oil transported by tank vessels in order to determine any correlational relationship. U.S. Coast Guard data was used to provide the volume of oil (petroleum) spilled into the marine environment each year by tank vessels. Data from the U.S. Army Corps of Engineers and the U.S. Department of Transportation's (US DOT) National Transportation Statistics (NTS) were used for the annual volume of oil transported via tank vessels in the United States. This data is provided in the form of tonnage and ton-miles, respectively. Each data set has inherent benefits and weaknesses. For the analysis the volume of oil transported was used as the explanatory variable (x) and the volume of oil spilled into the marine environment as the response variable (y). Both data sets were tested for correlation. A weak relationship, r = −0.38 was found using tonnage, and no further analysis was performed. A moderately strong relationship, r = 0.79, was found using ton-miles. Further analysis using regression analysis and a plot of residuals showed the data to be satisfactory with no sign of lurking variables, but with the year 1990 being a possible outlier.

Why, in the aftermath of 9/11, did a segment of the U.S. popular security experts, political elite, media, and other institutions classify not just al-Qaeda but Islam itself as a security threat, thereby countering the prevailing professional consensus and White House policy that maintained a distinction between terrorism and Islam?Why did this “politically incorrect” or counternarrative expand and degenerate into a scare over the country’s “Islamization” by its tiny Muslim population? Why is this security myth so convincing that legislators in two dozen states introduced bills to prevent the Shariah’s spread and a Republican presidential front-runner exclaimed:“I believe Shariah is a mortal threat to the survival of freedom in the United States and in the world as we know it”? This analysis offers a framework that conceptualizes popular discourses as highly interested fields of political struggle, deepens the prevailing characterization of this part of the U.S. popular discourse as “Islamophobia,” and analyzes how it has functioned politically at the domestic level. Specifically, it examines how a part of the conservative elite and institutions, political entrepreneurs already involved in the ongoing culture wars, seized upon Islam in the emotion-laden wake of 9/11 as another opportune site to advance their struggle against their domestic political opponents, “the Left,” and the more progressive societal institutions and culture in general.

In 1989 the U.S. Coast Guard promulgated regulations implementing Annex V to Marpol 73/78, which regulates the discharge of "garbage" from ships. Since that time it has become apparent that Marpol V, an international regime designed for the high seas, does not translate into a workable regime for the Great Lakes without some modification for the special problem of cargo residue discharges from dry bulk carriers. Application of Marpol V to the Great Lakes by the United States has also created an anomaly, because Canada has yet to do so, in large part because of serious concerns about its application to cargo residues on the Great Lakes. On September 22, 1993 the U.S. Coast Guard Ninth District put out an interim enforcement policy designed to provide a reasonable balance between the need to protect the environment of the lakes against any possible harm while taking account of the need for safe operation of commercial dry bulk carriers. At the same time, in cooperation with the Canadian Coast Guard Central Region and the U.S. National Oceanic and Atmospheric Administration, the U.S. Coast Guard Ninth District is developing better scientific information about the possible effects of cargo residues in order to build a scientific basis for a revised regulatory regime. As the scientific study progresses, the Ninth Coast Guard District continues to make modifications to the current enforcement policy, in consultation with Canadian Coast Guard Central Region, the scientific community, industry, and environmental groups. The final goal is a reasonably balanced and consistent regime on both sides of the lakes, in accordance with the mandates of the Great Lakes Water Quality Agreement.

When it had been decided that a Load Line Conference would be held in 1966, the United States drafted a complete proposed Convention which was based on the work of the United States Load Line Committee, a group sponsored by the Coast Guard, consisting of representatives of both government and the marine industry. This draft was circulated by Intergovernmental Maritime Consultative Organization to all governments in early 1964. Other governments then sent their comments on the U.S. proposal, and all comments were circulated together with the U.S. draft; the USSR prepared a complete draft also, and these were the two basic conference documents.

The Oil Pollution Act of 1990 has mandated that by the year 2015 all oil tankers operating in waters subject to jurisdiction of the United States must have double hulls. This paper examines the Act and the status of regulatory initiatives it has generated. Guidance for new hull construction and retrofit of existing vessels is outlined, and both IMO (International Maritime Organization) and U.S. Coast Guard requirements are discussed. Finally, the structural changes necessary to convert the U.S. Navy's T-AO Class oil tankers to meet the requirements of the Act are specified and illustrated.

With the passage of the Eighteenth Amendment, the federal government developed and enforcement strategy that charged the U.S. Coast Guard with preventing the illegal importation of liquor on the high seas surrounding the United States. The U.S. Customs Bureau guarded the nation's ports and borders, and the Prohibition Bureau working with state and local law enforcement patrolled the nation's interior. Congress, however, failed to appropriate the resources needed to enforce the law. The Coast Guard lacked enough ships to patrol U.S. waters, and faced uncertainty over the extent to which American authority extended out from shore. The Coast Guard picketed, tracked and trailed suspected rum runners, and disrupted the Rum Rows that developed off the coasts of American cities, but could not fully stop liquor smuggling.

In the last year, the Centers for Disease Control (CDC) published a loose-leaf manual, Guidelines for the Prevention and Control of Nosocomial Infections. One copy of the manual was sent to each hospital in the United States. Persons wanting additional copies were instructed to order them through the National Technical Information Service. In addition, the text of the manual was published in the March/April 1981, issue of INFECTION CONTROL.The manual contained the first of several guidelines that CDC is to publish for prevention of nosocomial infections. CDC is not presently prepared to distribute these guidelines to all U.S. hospitals, but expects to be able to do so within the next 12 months.A categorization scheme has been used to rank each of the recommendations in the guidelines. A full explanation of the scheme is in the manual and in the March/April 1981, issue of this journal.

ABSTRACT Congress departed from the international community to unilaterally enact comprehensive oil spill legislation, the Oil Pollution Act of 1990 (OPA). OPA legislates in several areas not covered by the international liability scheme for oil spills, including requirements for double-hull vessels, manning standards for foreign vessels, vessel response plans, and detailed and extensive provisions for liability for natural resource damages. Thus, it clearly provides better protection for the U.S. marine environment than would the international liability scheme. While OPA has encouraged the international community to take certain steps to provide greater protection, significant differences remain between OPA and the applicable international rules and standards. Protection of the marine environment on a global scale would be increased if the United States and the international community could bridge these differences.
