Agriculture Based Nonpoint PollutionLouisiana's Management Measures: AgricultureIVA. LOUISIANA MANAGEMENT MEASURES FOR AGRICULTUREINTRODUCTIONHeavy rainfall in Louisiana rinses a variety of pollutants off the land, sending them into our coastal waters. There pollutants accumulate, threatening organisms ranging from shrimp and oysters, to redfish, brown pelicans and bald eagles. In order to reduce the delivery of polluted runoff water from the land to coastal waters, Louisiana's Coastal Nonpoint Pollution Control Program, coordinated between many agencies and advisors, will ultimately 1) identify Best Management Practices (BMPs) appropriate for all applicable pollutant source categories, and 2) carry out a initiatives of public education, technical assistance, and development of enforcement protocols in order to get BMPs implemented on the land. Louisiana's Coastal Nonpoint Pollution Control Program will address the AGRICULTURE SOURCE CATEGORY, through all SEVEN management measure subcategories recommended by the National Oceanic and Atmospheric Administration (NOAA) and the Environmental Protection Agency (EPA). Louisiana is not proposing to exclude any management measures recommended by NOAA and EPA for this particular source category. The management measure subcategories that will be addressed in Louisiana's program are as follows:
APPLICABILITY of each of the seven management measures must be considered carefully and thoughtfully, with the understanding that some of the measures are only applicable to South Louisiana in a very limited sense. The management measure for Erosion and Sediment Control is broadly applicable to Louisiana agriculture, although all BMPs associated with that measure will not apply to all farms. The management measure for Confined Animal Facility, Small, is of very limited applicability because of the limited number and limited geographical distribution of any such facilities. The same restriction applies to the management measure for Confined Animal Facility, Large. The measure for Nutrient Management is broadly applicable to Louisiana agriculture, although all BMPs associated with that measure will not apply to all farms. The management measure for Pesticide Management is broadly applicable to Louisiana agriculture, although all BMPs associated with that measure will not apply to all farms. The measure Grazing Management must be applied very cautiously, as some of the associated BMPs are only applicable to managed pasture, and are not appropriate for open range or marsh fringe areas. The measure for Irrigation Management can only be applied in a limited sense, as a portion of South Louisiana's land is used for the production of leveed and flooded rice, but little other crop land could be considered "irrigated" as the term is understood in other areas of the country. ADMINISTRATIVE COORDINATION for agriculture is expected to be coordinated between the Louisiana Department of Natural Resources, and the Louisiana Department of Agriculture and Forestry, along with the Louisiana Department of Environmental Quality, and other entities (see section IIIC). TECHNICAL ASSISTANCE for agriculture will continue to be provided by a team of agencies featuring the Louisiana Cooperative Extension Service, and the Natural Resource Conservation Service, but also including the Louisiana Department of Agriculture and Forestry, the Louisiana Department of Environmental Quality, the Consolidated Farm Services Agency, and others (see section IIIA). MONITORING for compliance with BMP implementation is expected to be led by the Louisiana Department of Agriculture and Forestry. MONITORING of water quality will be led by the Louisiana Department of Environmental Quality, supplemented by the pesticide monitoring network of the Louisiana Department of Agriculture and Forestry, water sampling programs of the United States Geological Survey, and the Louisiana Department of Health and Hospitals (IIID). Best Management Practices (BMPs) for Agriculture for the LA Coastal Nonpoint Pollution Control ProgramIn Louisiana, agriculture is one of several land use categories generating nonpoint source pollution, some of which can be expected to reach coastal waters. In recognition of this, a cross-section of Louisiana's agricultural community has invested considerable time and effort in coordinating with governmental agencies to begin to identify effective and appropriate Best Management Practices (BMPs) for Louisiana, and to implement voluntary programs to reduce nonpoint source pollution. This is an ongoing process. Much work has been done thus far under the leadership of the Louisiana State University Agricultural Center toward identifying BMPs by commodity or livestock enterprise. The Best Management Practices Review and Development Program is a multi-agency program created in 1991 to evaluate the use of BMPs as a vehicle for environmental improvement on agricultural and forest lands. The program was conceptualized to be statewide, watershed based, and using site specific approaches for BMP applications. The BMP Review and Development Program was intended to help achieve voluntary producer implementation of economically achievable, effective BMPs, statewide. To date, BMPs associated with production of cotton, dairy, rice, sugarcane, feed grains, poultry production, and soybeans have been evaluated with written reports produced. BMPs pertaining to forestry production have also been evaluated and compiled by the Louisiana Forestry Association (LFA) in association with the Louisiana Office of Forestry (LOF) and the Louisiana Cooperative Extension Service (LCES). However, some words of caution are in order here.
Characterizing Agriculture in South LouisianaTo better understand the place of agriculture in the protection of Louisana's coastal waters, it is essential to grasp an important distinction. Firstly, in the state of Louisiana as a whole, agriculture is of critical importance to our economy and way of life. Agriculture contributed $8 billion to Louisiana's economy in 1994, with $3 billion in raw crop and livestock commodities, and another $5 billion in value added from processing. While cotton plays a pivotal role in providing jobs and supporting the tax base in North Louisiana's East Carroll Parish, sugar cane plays a comparable role in sustaining a viable economy in South Louisiana's Assumption Parish. A healthy appreciation for the agricultural community influences governmental decision-making across the entire state of Louisiana. However, in much of South Louisiana near our coastal waters, there is relatively little land capable of supporting crop cultivation or other intensive forms of agriculture. South Louisiana contains 40% of the coastal marshes of the contiguous United States. Projecting into low-lying wetlands are fingers of higher land, often remnants of natural levees left behind by shifts in the Mississippi River delta locations over thousands of years. High ground is the exception in South Louisiana. Local geography is dominated by flood plain, swamp and marsh. What that means is that well-drained land is not plentiful, and is valued at a premium. Any particular use of this land must pay its own way with substantial returns to investment, or otherwise be bought out by some competing land use. The fact that any agriculture at all remains in the eastern half of South Louisiana attests to the economic clout of the agricultural enterprises there. The major agricultural commodities produced in South Louisiana are sugar cane, rice, dairy farming, and beef cattle. Dairying, may be of greater impact than beef production, but dairying is geographically localized to the "Florida Parishes" north of Lake Pontchartrain. Sugar cane is one of the highest value agricultural commodities in all of Louisiana. In 1993, the state of Louisiana harvested 360,000 acres of sugar cane, which increased to 383,000 in 1994. Although sugar cane is limited by climate to South Louisiana, sugar cane requires well-drained soils, and the majority of its farms are located outside of Louisiana's coastal zone (see map). Sugar is produced on relatively large tracts, with producers in the leading parish, Iberia, averaging 417 acres in cane per farm in 1993. Reports by the Louisiana Dept. of Agriculture and Forestry indicate that many Best Management Practices tend to be used on cane fields, but questions have been raised as to the applicability of putting tracts of this size into cover crops to span fallow periods. The Louisiana Dept. of Environmental Quality and the Barataria-Terrebonne National Estuary Program have set up both research and demonstration projects to promote sugar cane BMP implementation. Some preliminary findings of these projects seem to suggest that banded applications of pesticides can achieve reduced levels of pesticide usage, while maintaining adequate levels of control. A new cane variety was recently released by the experiment station with improved resistance to both insects and disease, and offering the hope of needing significantly less pesticide. Local representatives of the American Sugar Cane League have been among the most active citizens in providing input into the development of the Louisiana's CNPCP thus far. Rice is the other major crop in South Louisiana. It was the fourth largest crop commodity in all of Louisiana in 1993 by value. The total statewide harvested acreage, 530,000, was divided between seven parishes of Southwest Louisiana (327,000 acres in that subregion; Vermilion largest parish with 90,700 acres); and over 20 parishes farther to the northeast, extending to the Arkansas state line. In 1994 LDEQ surveyed rice producers in the Bayou Queue de Tortue area regarding BMPs in use and found that producers intended to continue to utilize BMPs even without cost-sharing money. In addition to LDEQ activities in SW LA, nonregulatory programs in the area include the Operation Quackback Program, jointly sponsored by Louisiana Cooperative Extension Service, the Louisiana Farm Bureau Federation, and the Louisiana Rice Growers Association. This program promotes the simple practice of holding water on rice fields over the winter months, providing supplementary habitat for migratory waterfowl, with a related increase in consumption of "red rice" weed seeds. Reduction of this weedy pest should translate into less herbicide needed in the spring. Additional conservation benefits of the practice are realized by allowing time for fine sediments to settle out, and protecting the soil surface from the erosive force of hard Louisiana rains with a cover of standing water. Dairy farms constitute the most signifcant form of Confined Animal Facility in proximity to Louisiana's coastal zone. Dairy operations are found in watersheds tangent to Louisiana's coastal zone in three parishes: Livingston, St. Tammany, and Tangipahoa. While these parishes (along with Washington, and St. Helena Parishes) have almost 80% of all Louisiana's dairy farms, only a few of their dairy farms (three?) are located within the coastal zone. Since 1989, there has been a vigorous, voluntary dairy BMP implementation program in this area, involving multiple agencies and organizations. The effort has resulted in the installation of no-discharge lagoons to handle dairy wastes. The current results of the program indicate that in Tangipahoa Parish alone, where one-half of the area's dairies are located, 120 lagoons have been installed, and 45 lagoons are in the planning stage. When dairy closures are added to these numbers, 73% of the parish's 270 dairies currently have or are planning no-discharge lagoon installation for handling their wastes, or have ceased operation as a dairy farm. The adjoining parishes are also participating in the current BMP implementation program. Beef cattle are raised all over Louisiana in small cow/calf farm herds, and in Southwest Louisiana in lower density open range conditions. Concentrated Animal Facilities, in the form of feed lots, are virtually nonexistent in South Louisiana. The statewide mean beef herd size was only 45 head in 1993. That figure jumps to 85 head in Cameron Parish, the largest parish in the state, by area, where the cow-to-person ratio is almost 4:1, however, those herds are dispersed over the corresponding larger areas, giving low densities of animals. This is an important distinction: grazing management measures designed for intensively managed pastures of the Eastern United States are of limited applicability to low animal density range conditions. Further, management measures designed for protecting well-defined water courses are not necessarily applicable to regions of high rainfall and flat topography where the borders of streams and wetlands are quite variable. Louisiana may need to break its grazing BMPs, currently under development, into separate subsets for "range" and "pasture." Some livestock raising BMPs are eligible for USDA (CFSA) cost-share money. Earthmoving for construction of cattle walks through the marshes is regulated by Coastal Use Permit from LDNR, and (404/401) permits from USACOE and LDEQ. Truck produce (annual fruits and vegetables), and citrus fruit operations are similar to dairies in that a relatively small acreage is dedicated to these land uses for the state as a whole, yet much of what we have is concentrated geographically (Tangipahoa Parish, the southern half, and Plaquemines Parish). The annual fruits and vegetables, mainly strawberries, peppers, cucumbers, and cabbage, are raised in some proximity to coastal waters (ten to thirty miles from the brackish lakes Pontchartrain and Maurepas) and the intensity of inputs and polluted runoff potential from this clustering could be significant. However, the positive side of the clustering should be recognized, in terms of efficiencies in public outreach, demonstration, and technical assistance efforts. All of these efforts are supported by the LSU Agricultural Center's Hammond research station, dedicated to truck crops and horticulture. In 1993 all of Tangipahoa Parish had 250 producers of strawberries on 1000 acres, and 50 producers of bell peppers on 900 acres. The largest parish for citrus fruit orchards, Plaquemines, had 150 producers of citrus fruits, with a total area in production of only 510 acres. The Best Management Practice Review committee for commercial fruits and vegetables began a series of meetings in 1994, and a report of their findings is forthcoming. Soybeans were more important in South Louisiana in the mid-and late-eighties than they are now. The $7.50 per bushel beans of 1988 had fallen to $5.50 in 1991 and acreages planted tend to correspond with these market trends (from 2.0 million acres statewide, down to 1.0 million acres). In addition, Louisiana soybean production has been subjected to increasing biological pressure by pests such as red crown rot, stem canker, and root knot nematodes. Soybeans have been grown on a variety of soils, which adds up to a menu of alternative land uses available to replace soybeans. Statewide, cotton, corn, and to a lesser extent, hay, have increased at the expense of soybeans. But in South and Central Louisiana, tracts of poorly-drained bottomland cleared for beans in the 1970s were prime sites to let revert back to non-agricultural vegetation when opportunities appeared with the Wetland Reserve Program, the Conservation Reserve Program, and the Forestry Incentive Program. In 1988 Vermilion/Cameron/Calcasieu Parishes combined to harvest 138,500 acres of soybeans for grain. In 1991 the three parish total was down to 7,200 acres. It rebounded somewhat to 52,400 acres in 1993, and fell to 37,000 acres in 1994. II. EXISTING NPS PROGRAMS IN LOUISIANA: REGULATORY AND NONREGULATORYREGULATORY PROGRAMSThe Dept. of Environmental Quality's oversight authority over discharges into surface waters (402 program) is documented in Section 402 of the Clean Water Act. A discharge permit is required for any point source discharge into waters of the state. This includes discharge from dairy lagoons, non-irrigation agricultural lagoons, catfish, crawfish, and alligator farms, and from rice seed soaking operations. All other agricultural activities are exempt from Louisiana state water discharge permits. There is an anti-degradation provision in the regulations to not allow state waters to go below current designated use support levels. This provision can be used to bring violators into compliance. Whether this authority could be extended to irrigation tailwaters remains subject to interpretation. The Louisiana Natural and Scenic Rivers SystemThe Louisiana Natural and Scenic Rivers System is one of the nation's largest. It encompasses 51 streams or stream segments and is over 1,500 miles in length. There are nine Scenic Rivers within the present boundaries of the Louisiana Coastal Zone. The System was proposed in the late 1960's and was brought into existence in the early 1970's with the passage of the Louisiana Natural and Scenic Rivers Act (La.R.S.56:1840 et seq.). The Act established a regulatory program and empowered the Secretary of the Louisiana Department of Wildlife and Fisheries (LDWF) to administer the System through regulation and permits. This regulatory program prohibits the following activities on all designated Scenic Rivers: channelization; channel re-alignment; clearing and snagging; impoundments of any type; and commercial clear-cutting of timber within 100' of the low water mark. Activities which may have a direct, significant or ecological impact on the streams and would thus require a "Class B" permit includes the following: bridge, pipeline and powerline crossings; bulkheads, piers, docks and ramps; waste water discharges; and land development adjacent to the stream. Any other activity that may have a direct, significant, ecological impact on the stream or its tributaries or distributaries is subject to regulation by permit by the Department of Wildlife and Fisheries. Scenic Rivers permits require the evaluation of twelve criteria for issuance. These include the following: cultural associations; historical/archaeological artifacts; economic changes; wilderness/rural qualities; scenic/aesthetic values; recreational opportunities; ecological systems; fish and other aquatic life; wildlife species; botanical elements; geological/hydrological features; and water quality/quantity. The Scenic Rivers System Permit is issued by the LDWF with a multi-agency review by the LDWF, Office of State Planning and Budget, Louisiana Department of Environmental Quality (LDEQ), and the Louisiana Department of Agriculture and Forestry (LDAF). All permit applications are reviewed on a case-by-case basis, and most involve on-site inspections of the project area. The monitoring and enforcement of the permits will be handled by LDWF agents through site investigations and inspections, surveillance and citizen complaints. Enforceable policies and mechanisms for this program include criminal penalties with fines and civil penalties with fines and adjudication. Penalties include: up to $1,000 fines for each violation; suspension, annulment, withdrawal or revocation of the permit; institution of civil proceedings in district court; and issuance of cease and desist orders, compliance orders, injunctions or other appropriate relief. The program currently issues 15-20 permits per year. The LDNR is discussing a Memorandum of Agreement with LDWF to oversee implementation of certain provisions of the CNPCP, to monitor and educate staff, contacts, and permittees on the provisions of the program, and to report noncompliance to the LDNR on at least a quarterly basis. The LDWF may incorporate said provisions as special conditions to their Scenic Rivers Permits and other projects until such time as these nonpoint pollution abatement measures become standard permit conditions. A "bad actor" provision for agriculture, forestry, or hydromodification activities is expected to be available to be invoked when the need arises in the future. The Louisiana Natural and Scenic Rivers System Permit in conjunction with the Louisiana Scenic Rivers Act provide some enforceable policies for the 6217(g) management measures. It requires scenic stream management plans (MM 2 II.C.); it requires permits for "waste water discharges" (MM 2 II.B.,C., and F.) and its permit evaluation process would give strong consideration to most of the BMPs recommended in MM 2 II. A for Erosion and Sedimentation Control, and in MM 2 II.D. for Pesticide Management. Louisiana Department of Natural Resources (LDNR) Coastal Use Permit ProgramThe Coastal Management Division (CMD) of the Louisiana Department of Natural Resources (LDNR) is charged with implementing the Louisiana Coastal Resources Program under authority of the Louisiana State and Local Coastal Resources Management Act of 1978 (Act 361, La.R.S.49:214.21). Under this authority, the Coastal Use Permit Program (CUPP) has been established by the CMD to help ensure the management and reasonable use of the state's coastal wetlands. The CUP program carries the authority to enforce either legal or administrative procedures, including levying fines, issuing cease and desist orders, and requiring mitigation or restoration. The CMD Enforcement and Monitoring section monitors permitted activities in the coastal zone for compliance with permit conditions, and patrols by air, land, and water the entire coastal zone for unauthorized activities. The CUP Program has oversight for land use activities in the designated coastal zone that involve dredging, fill, or other earth-moving or drainage impacting activities. Activities that may require a coastal use permit include dredge and fill projects, sewage treatment plant siting, waste-water discharge, drainage projects, pumping facilities, marsh management activities, water level control, levee construction, solid waste dump siting, roads and bridges, park siting, freshwater diversion, and mosquito control. Exempt from the program are silvicultural operations, as well as activities in leveed fastlands, in areas above the 5-foot contour interval, and on lands of federal jurisdiction. Agricultural activities are excluded from the program where carried out in areas that traditionally have been used for agriculture. The Louisiana Administrative Code 43 § 723 (B.7 a-b) reads: Agriculture, forestry, and aquaculture activities on land consistently used in the past for such activites shall not require a coastal use permit provided that: The activity is located on lands or waters which have been used on an ongoing basis for such purposes, consistent with normal practices, prior to the effective date of the Act 361 of 1978; the activity does not require a permit from the U.S.Army Corps of Engineers and meets federal requirements for such exempted activities, and; the activity is not intended to, nor will it result in, changing the agricultural, forestry, or aquacultural use for which the land has been consistently used for in past to another use. The exemption includes but is not limited to normal agricultural, forestry, and aquacultural activities such as plowing; seeding; grazing; cultivating; insect control; fence building and repair; thinning; harvesting for the production of food, fiber, and forest products; maintenance and drainage of existing farm, stock, or fish ponds; digging of small drainage ditches; or maintenance of existing drainage ditches and farm or forest roads carried out in accordance with good management practices. Presently subject to regulation by permit are construction of cattlewalks and excavation for new crawfish ponds, but there were no permit applications made for either of these categories during the past year of October 1993 to November 1994. Agriculture would be regulated under the CUP Program when the proposed land uses involve earth-moving in the coastal zone for new developments. The coastal management guidelines used to issue coastal use permits specify that "linear facilities," which includes roads, shall be planned using the best practical techniques to minimize disruption of natural hydrologic and sediment transport patterns, sheet flow and water quality (La. Admin. Code tit.43:I.705[I]), and thus would be most applicable to the management measure for Erosion and Sediment Control, management measure 2 II.A. While the program does not generally exert authority over agriculture in coastal Louisiana, there appears to be room in the wording of the code for a stricter interpretation, and extension of such authority to address other of the 6217 (g) management measures for agriculture. LDAF Louisiana Pesticide Law and Applicator Certification ProgramThe Federal Insecticide, Fungicide and Rodenticide Act as amended in 1972 (FIFRA) requires individuals who apply restricted use pesticides to be certified applicators. Likewise, the Louisiana Pesticide Law (La.R.S.3:3201) states that: "No person shall apply or supervise the application of any restricted use pesticide as a private applicator unless that person has the proper certification." This certification, for both commercial and private pesticide applicators, is necessary in order to buy, use, or supervise the use of restricted pesticides. Certification is issued after the applicant has satisfactorily passed an examination or has satisfactorily demonstrated knowledge of the laws, rules and regulations, and safety practices governing the sale and application of restricted use pesticides. Examinations are given and certifications are issued by the Louisiana Department of Agriculture and Forestry (LDAF). The Louisiana Cooperative Extension Service (LCES), by cooperative agreement, is responsible for the training necessary to become a certified applicator. Workshops are conducted covering all aspects of pesticide use as delineated in 40CFR171. Applicators must be recertified every three years. The Louisiana Pesticide Applicator Certification Program addresses the 6217 (g) management measure for agriculture, 2 II.D., Pesticide Management. U.S. Army Corps of Engineers 404 Permit ProgramThe Department of the Army regulatory program is one of the oldest in the federal government. The legislative origins of the program are the Rivers and Harbors Acts of 1890 (superseded) and 1899 (33 U.S.C.401 et seq.). Various sections establish permit requirements to prevent unauthorized obstruction or alteration of any navigable water of the United States. In 1972, amendments to the Federal Water Pollution Control Act added what is commonly called Section 404 authority (33 U.S.C.1344) to the program. The Secretary of the Army, acting through the Chief of Engineers, is authorized to issue permits, after notice and opportunity for public hearings, for the discharge of dredged or fill material into waters of the United States at specified disposal sites. Selection of such sites must be in accordance with guidelines developed by the Environmental Protection Agency in conjunction with the Secretary of the Army. These guidelines are known as the 404 (b) (1) Guidelines. The Federal Water Pollution Control Act was further amended in 1977 and given the common name of "Clean Water Act." Section 10 (33 U.S.C.403) contains the most frequently exercised authority in the Rivers and Harbors Act. Section 10 covers construction, excavation, or deposition of materials in, over, or under navigable waters, or any work which would affect the course, location, condition, or capacity of those waters. Navigable waters in the River and Harbors Act of 1899 are defined (33 CFR 329) as, "those waters that are subject to the ebb and flow of the tide and/or are presently used, or have been used in the past, or may be susceptible to use to transport interstate or foreign commerce." The Clean Water Act uses the term "navigable waters" which is defined (Section 502 [7]) as "waters of the United States, including the territorial seas." Section 404 jurisdiction then is defined as encompassing Section 10 waters plus their tributaries and adjacent wetlands and isolated waters where the use, degradation or destruction of such waters could affect interstate or foreign commerce. The discharge of dredged or fill material into waters of the United States requires a Section 404 permit. This includes return water from dredged material disposed on the upland and generally any fill material (e.g., rock, sand, dirt) used to construct fast land for site development, roadways, or erosion protection. Normal farming, silviculture, and ranching activities such as plowing, seeding, cultivating, minor drainage, harvesting for the production of food, fiber, and forest products, or upland soil and water conservation practices are exempt under the 404 permitting process [CWA, Sec404 (f) (1)]. However, agricultural activities in designated wetland areas require a federal permit. Nonpoint source agricultural activities related to road construction may involve point source discharges of dredged or fill material and also may require a Section 404 permit{LAC tit.33:IX.301(M)(2)(a)}. The federal 404 permit requires a 401 Water Quality Certification issued by the Louisiana Department of Environmental Quality (LDEQ). This is a regulatory program administered by the state of Louisiana. The 401 Water Quality Certification's recommendations are incorporated into the Section 404 permit, and is then monitored through the USACOE's federal program as conditions of the federal permit. The CWA Section 404 permit also requires that in addition to applying the state's approved Best Management Practices to the permitted activity, fifteen baseline provisions mandated by the USACOE must also be implemented. SFWS Endangered Species Act/Critical Habitat IdentificationThe Endangered Species Act was enacted in 1973 to provide a means whereby the ecosystems upon which endangered species and threatened species depend would be conserved and also to provide a program for the conservation of such endangered species and threatened species. The Act is regulatory, nationwide in scope, and provides protective regulations for threatened species; recovery plans for the conservation and survival of endangered and threatened species; and includes penalty and enforcement provisions for violations of the Act. The U.S. Fish and Wildlife Service implements and has oversight for the Endangered Species Act in Louisiana. Provisions of the Endangered Species Act relates to the following 6217(g) management measures and their components: 2 II.A.u."wetland and riparian zone protection," and 2 II. D. on pesticides, by providing an enforceable mechanism to provide protection for threatened or endangered aquatic species habitat areas. Worker Protection Standard for Agricultural PesticidesThe new Worker Protection Standard for Agricultural Pesticides issued by the U.S. Environmental Protection Agency (EPA) consists of revised regulations intended to reduce the risk of pesticide poisonings and injuries among agricultural workers and pesticide handlers through appropriate exposure reduction methods. These new regulations expand the requirements for issuing warnings about pesticide application, use of personal protective equipment, and restrictions on entry to treated areas. New requirements were added for decontamination, emergency assistance, maintaining contact with handlers of highly toxic pesticides, and pesticide safety training. Agricultural workers, including those in forest related cultivation and harvesting tasks, and pesticide handlers are targeted by this new Worker Protection Standard. New WPS provisions are intended to: (1) eliminate exposure to pesticides, (2) mitigate exposures that occur, and (3) inform employees about the hazards of pesticides. The Louisiana Cooperative Extension Service (LCES) is involved in an extensive statewide outreach program to inform agricultural producers of what they must do to be in compliance with this program. The 6217(g) management measure 2 II.D is addressed by this worker protection standard. It applies to agricultural workers and pesticide handlers who are involved in pesticide applications conducted as a part of normal agricultural activities. As stated, all workers involved in cultivation and harvest of plants in forests or those that handle agricultural pesticides are covered. NONREGULATORY PROGRAMSLake Pontchartrain Basin FoundationThe primary goal of the Lake Pontchartrain Basin Foundation (LPBF) is to develop a comprehensive plan to clean up and restore water quality in the Pontchartrain Basin. This is to be done in cooperation with the U.S Environmental Protection Agency, with a grant for $500,000. The LPBF is working with the local and state agencies to incorporate any existing legal or regulatory authority into the plan. The LPBF was founded under La Legislative Act 716, and began operations in 1989. They are currently working with the NRCS and the dairy farmers north of the lake, on a plan to continue installation of no-discharge lagoons to reduce the amount of dairy waste entering the lake. This program started in March of 1993 and a number of farmers have signed up to participate. The LPBF has several ongoing projects for improving the lake's habitat that include constructed wetlands creation, freshwater diversion projects, and upgrading small municipal sewage systems north of the lake.

1)
2)Louisiana has at least four programs with broad authority for more stringent regulation than has been exercised heretofore. These programs should not be dismissed lightly, for at least two reasons. Firstly, in virtually all times and places, and especially in the present political atmosphere, there is little corporate will to add additional laws and bureaucratic instruments; laws in place may constitute "gold mines" of regulatory resources that could be utilized to some significant positive effect. Secondly, better use of these existing regulatory powers can be coaxed out by 1) setting up memoranda of agreement that explicity spell out agency actions to follow, and 2) funding targeted to enable these actions to occur. The four highlighted programs -- all with shortcomings, all with potential -- are the Soil and Water Conservation Districts, the Conservation Compliance provision linking USDA (CFSA) support programs, the Dept. of Environmental Quality's oversight authority over discharges into surface waters, and the Louisiana Natural and Scenic Rivers System. In addition there are regulatory entities such as the Louisiana Pesticide Commission, and the Louisiana Fertilizer Commission whose scope is much less broad, but whose authority is powerful over a narrower range of activities.
