To disseminate the findings of Phase I, this Operations Planning Manual has been prepared for use by FWPCA personnel involved in oil-spill cleanup operations. Full-scale testing of the beach restoration procedures described in this manual will be conducted during Phase II of the study, and a final report describing the results of the entire study will be issued on July 1, 1970, to supercede this document. The objectives of the research study are to be accomplished in two phases, each consisting of several tasks as follows: PHASE I Task I Review existing reports on recent oil pollution incidents and other available information to determine the magnitude of beach contamination and previous methods utilized in beach restoration operations. Task II Survey commercially available equipment and obtain information on pertin- ent performance characteristics; design candidate beach restoration procedures, and identify possible limitations of equipment. Task III Conduct preliminary evaluation tests to determine operating character- istics and performance of the equipment in removing a thin layer of sand under ------- various beach conditions; determine the necessary modification and cost of modifications to improve the performance of the equipment. Task IV Prepare a test plan for the full-scale testing of the candidate beach restoration methods and develop performance criteria and specifications for the various classes of equipment to be evaluated. PHASE II Task I Conduct full-scale field tests to evaluate the operating plans, methods, and equipment selected in Phase I. Evaluate effectiveness of modifications to equipment. Performance criteria to be measured for each procedure and equipment combination evaluated shall include: (a) Efficiency with which each procedure/equipment collects (and/or spills) oil-contaminated material. (b) The ratio of oil to inert material in the mixture collected. (c) The cost per unit of oil collected and unit of beach area cleaned. (d) Capability of the equipment to operate under a variety of beach conditions. (e) Performance characteristics at various speeds, blade angles and depths of cut. ------- BEACH RESTORATION PROCEDURES The surface conditions and topography of a beach contaminated with oil and the manner in which the oil has been deposited onto the beach will dictate the choice of equipment to be utilized and the operating procedures to be followed. The Phase I preliminary evaluation tests indicated that several restora- tion procedures seem to provide considerable savings in effort and cost over some methods previously used. These procedures are listed in Table 1. The restoration procedures described herein are those recommended for the restoration of relatively flat, sandy beaches contaminated under one or both of the following situations: a. Beach material uniformly contaminated with a layer of oil up to the high-tide mark and/or deposits of oil dispersed randomly over the beach surface. Oil-deposit penetration is limited to approximately 1 in. b. Agglomerated pellets of oil-sand mixture or oil-soaked material, such as straw and beach debris, distributed randomly over the surface and/or mixed into the sand. The procedures tested utilize the following equipment, singly or in combination: • Motorized Graders • Motorized Elevating Scrapers • Front End Loaders • Conveyor-Screening Systems Based on the visual observations made during the Phase I preliminary evaluation tests described in ANNEX I, and the overall production rates calculated for each equipment type evaluated, the following conclusions are offered: ------- Table 1 RECOMMENDED RESTORATION PROCEDURES RESTORATION PROCEDURE METHOD OF OPERATION A. Combination of motorized grader and motorized elevating scraper Motorized graders cut and remove surface layer of beach material and form large windrows. Motorized scrapers pick up windrowed material and haul to disposal area for dumping or to unloading ramp-conveyor system for transfer to dump trucks. Screening system utilized to separate beach debris such as straw and kelp from sand when large amounts of debris are present. B. Motorized elevating scraper Motorized elevating scrapers, working singly, cut and pick up sur- face layer of beach material and haul to disposal area for dumping or to unloading ramp-conveyor system for transfer to dump trucks. Screening system -utilized to separate beach debris such as straw and kelp, from sand when large amounts of debris present. C. Combination of motorized grader and front end loader Motorized graders cut and remove surface layer of beach material and form large windrows. Front end loaders pick up windrowed material and load material into following trucks. Trucks remove material to disposal area or to conveyor-screening system for separation of large amounts of debris from sand. D. Front end loader Front end loaders, working singly, cut and pick up surface layer of beach material and load material into following trucks. Trucks remove material to disposal area or to conveyor-screening system for separation of large amounts of debris from sand. ------- 1. A motorized grader and motorized elevating scraper working in combination provide the most rapid means of beach restoration; and in addition, their use results in the removal of the smallest amount of uncontaminated beach material. (a) The optimum moldboard (blade) angle for the motorgrader, in which minimum spillage occurred while windrowing sand, was found to be 50 deg from the perpendicular to the direction of travel. At smaller angles the sand builds up on the mold- board and spills around the leading edge. At larger angles, the operator loses the fine control of the blade and has difficulty keeping a constant depth of cut. (b) Straw spread on beach areas is easily windrowed by the motorized grader and removed by the motorized elevating scraper. Removing straw directly with a motorized elevating scraper posed no problem. (c) Kelp, seaweed and similar debris does not interfere with the operation of either the motorized grader or motorized elevating scraper. (d) On beaches of very coarse sand, both the rubber-tired motorized grader and motorized elevating scraper may become immobilized while conducting beach restoration operations. For such beaches, flotation tires or rubber-belted half tracks on the motorized grader and tracked prime movers to assist the motorized elevating scraper in loading or cutting operations would be required. (e) When a motorized elevating scraper is picking up a windrow or making a thin cut, a certain amount of spillage occurs around each edge of the scraper bowl. Although the spillage could not be considered excessive for normal earthmoving operations, it would be undesirable when conducting beach restoration operations. ------- 2. A front end loader mounted on a crawler tractor is the most in- efficient apparatus. In addition more spillage occurs with its use than with any other equipment. These results can be extrap- olated (we believe) to apply also to bulldozers. 3. A non-elevating motorized scraper will not operate efficiently on beach areas unless a tracked prime mover is used either as the principal source of power or as a pusher to assist in loading. A thin cut is difficult to maintain, and excess spillage occurs when loading. 4. Beach restoration operations on backshore areas become very difficult due to the looseness of the sand. Procedures for minimizing the oil-contamination of backshore areas should be instituted at the first indication of a possible shoreline pollution event. Under normal tide conditions, a berm or dike at the high-tide mark can prevent oil from contaminating back- shore areas. 5. Conveyor-screening systems can be effectively utilized to: (a) load oil-contaminated material into trucks for transport to disposal areas, and (b) separate oil-contaminated debris (i.e., straw, kelp, seaweed) from oil-contaminated sand. 6. There has been little to no effort towards the systematic col- lection of data needed to accurately determine the cost and effectiveness of previous beach restoration operations. (See Annex II for Proposed Data Requirements). In the following sections, descriptions of each type of equipment are given, including (a) principle of operation, (b) applicability, and (c) operational procedures. Included in each section are tables of equipment specifications and operating costs obtained from equipment manufacturers. The tables do not include all models and makes in each equipment category however, the listed models constitute the majority of such equipment presently utilized in construction activities. ------- MOTORIZED GRADERS Principle of Operation Motorized graders (Fig. 1) are designed to move quantities of material short lateral distances by the process of side casting. They are not generally used to haul material in the direction of travel. When the blade is set at an angle, the material that is cut and pushed ahead of it tends to be deflec- ted to one side with a rolling and sliding action. The curve of the moldboard (blade) is designed to promote the rolling and sliding action of the material as it moves across the blade. The size of the windrow created by the material as it comes off the blade is dependent upon the depth of cut, angle of the blade and the con- dition of the material being moved. Under certain soil conditions, a motor- ized grader is capable of making successive passes, i.e., picking up a windrow and simultaneously cutting and moving the cut material along with the previous windrow. After the windrows are formed, they must be removed from the area by some other means. Fig. 1. Motorized Grader ------- Applicability Motorized graders are most efficient when operating on relatively flat areas of cohesive soil, firm but not hard, and on relatively long narrow areas. A uniform cut is difficult to maintain under conditions where rocks are present in the surface layer. For the removal of oil-contaminated sand, the motorized grader would be most efficiently used on the firmly packed beach area lying between the high and low tidal zones. A major problem encountered with a motorgrader is its inability to maintain traction when operating on a beach of low-bearing-strength sand. Flotation tires on all wheels will overcome this problem on most beaches. A set of flotation tires and rims to fit most models and makes of motor- graders would cost approximately $2400. An alternative to flotation tires is the addition of rubber-belted half-tracks, which would fit over the drive wheels on each side of the grader. These half tracks are a standard shelf item and have been utilized extensively on agricultural machinery. A set of rubber-belted half-tracks can be installed for approximately $1000. The front wheels of a motorgrader will, in some instances, depress the beach surface to a depth greater than the depth of cut being taken, thus leaving two tracks of oil in the cleared area. The magnitude of this "spillage" will depend upon the bearing strength of the sand, depth of cut, and amount of oil on the surface. Moldboard modifications to eliminate this spillage would consist of extensions to the cutting edge positioned as shown in Fig. 2. ------- Fig. 2. Moldboard Modifications Operational Procedures Operational procedures for motorized graders conducting beach restoration operations follow: (1) Set moldboard (blade) at a 50-deg angle perpendicular to the direction of travel. angle measured (50 ) blade direction of travel (2) Set depth of cut at depth of oil penetration (1/2 to 1 in.). (3) Operate grader in second gear (3 to 4 mph). (4) Commence grading 1st pass on oil-contaminated material furthest inshore, casting windrow parallel to surfline. Continue grading to end of contaminated area or approximately 200 to 300 yards in distance. ------- (5) Return grader to starting point by backtracking on cleaned area. (6) Reposition grader for 2nd pass so as to pick up Ist-pass windrow and cast 2nd-pass windrow parallel to surfline (see Fig. 3). (7) Return grader to starting point by backtracking on cleaned area. (8) Reposition grader for 3rd pass so as to cast a windrow from surfline side onto 1st- and 2nd-pass windrow as shown in Fig. 4. A three- pass windrow is the optimum for pickup by a motorized elevating scraper (see Fig. 5). Limit height of windrow to ground clear- ance of tractor. Note: Optimum rate of operation for smooth firm beaches is 1/2 to 1/3 hr/acre. Specifications of motorized graders are given in Table 2. Equipment manufacturer designations are given in Table 3.

They are equipped with self-loading elevators that pick up the cut material and dump it back into the hopper. In some materials, such as sand, they pick up material more easily than a standard non-elevating scraper that relies on the resistive force of the undercut material to fill the hopper. Fig. 6. Motorized Elevating Scraper Applicability Motorized elevating scrapers are most effective in clearing large areas that are relatively flat; however they can operate on sloped beaches. The motorized elevating scraper is the most efficient type of equipment for picking up windrows left by a motorized grader. The maximum size of the windrow should be restricted to the height of the ground clearance of the tractor, which ranges from 12 to 24 in. for most tractors. On beaches exhibiting low bearing strength, the motorized elevating scraper, in its present configuration, will become immobilized in the sand. Two possible methods that will overcome the immobilization problem are: 15 ------- (1) Use of a non-self-propelled elevating scraper (see Table 5), pulled by a tracked bulldozer or front end loader. The use of a crawler tractor increases traction greatly and would permit scraper operation on beaches of low bearing strength. (2) Use of a pusher unit (i.e., a tracked or wheeled bulldozer) as an additional prime mover to push the elevating scraper unit, or use of a tandem-drive elevating scraper, such as the WABCO BT 33F, which has both pusher and puller prime mover units as standard equipment. Operational Procedures Operational procedures for motorized elevating scrapers working singly or in combination with a motorized grader are listed below. Since a motorized grader is capable of producing windrows continuously, several motorized elevating scrapers can be utilized simultaneously to pick up windrows. • Operating in combination with motorized graders (1) Position elevating scraper so as to straddle the windrow formed after three passes by the motorized grader (see Fig, 7). Lower cutting edge of bowl to cut to depth of oil penetration (1/2 in.). (2) Operate the scraper in 1st gear (low range) and pick up windrow, keeping elevator flights moving after bowl has filled up. (3) Proceed to unloading area (keeping elevator flights moving). Rates of operation depend upon distance to unloading area. • Operating singly (1) Commence operations on oil-contaminated material farthest inshore. Operate parallel to surfline. 16 ------- (2) Set depth of cut to depth of oil penetration (1 to 2 in.) or just to skim surface if only oil-contaminated debris to be removed. Figures 8 and 9 show the results of picking up beach debris and Figs. 10 and 11 show the results of removing straw from a test area (3) Operate scraper in 1st gear (low range). (4) Length of pass dependent upon size of scraper bowl. Keep elevator flights running after bowl is filled. (5) Proceed to unloading area (keeping elevator flights moving). Note: Rate of operation for one elevating scraper is 3/4 to 1 hr/acre when removing windrows and 1 hr/acre when operating singly. Rates are based on a haul distance of 200 ft (see Fig. 17, Annex I). Table 4 lists the specifications of the motorized elevating scraper. Table 5 presents a similar listing for the crawler tractor-drawn elevating scrapers.

The front loader (bucket) may be carried by any type of tractor, crawler tractor, or four-wheel-drive or two-wheel- drive rubber-tired tractors. Crawler tractors and four-wheel-drive tractors are used for heavy service and two-wheel-drive models for lighter work. Buckets are made in different sizes and weights for various types of materials and work conditions. Bucket capacity will depend upon the size and type of tractor on which it is mounted. Buckets for crawler tractors range from 3/4 to 4 cu yd. Wheeled tractors have both smaller and larger buckets. The bucket is loaded by the forward travel of the tractor. Most load- ing is done with the bucket flat or tilted at a slight downward angle. The flat position is best for loading a quantity of loose material. The amount picked up in the bucket will vary with the consistency of the material, the slope of the area worked on, and the skill of the operator. Applicability From the results obtained during the preliminary evaluation tests con- ducted in Phase I, and analysis of previous beach restoration operations, it is recommended that front end loaders be utilized only for loading material from windrows formed by motorized graders or from stockpiles into trucks. Their operations on oil-contaminated beach areas should be kept to a minimum, especially when utilizing crawler-tractor mounted front end loaders, which have been found to grind the oil several feet into the sand. Front end loaders equipped with slot buckets could be utilized in remov- ing large quantities of oil-contaminated debris, such as delp, driftwood, etc. Slot buckets would allow loose sand to fall away through the slots. 23 ------- Operational Procedures Operational procedures for front end loaders working singly or in combination with a motorized grader are listed below. Several front end loaders will be required to remove windrows formed by a single motorized grader. (1) Utilize 4-in-l type bucket if available (see Fig. 13). (2) Operate tractor in 1st gear while loading. (3) To minimize spillage, while scraping, only fill bucket 1/3-1/2 full. (4) Minimize traffic over oil-contaminated area when using tracked loader. Note: Rate of operation for one front end loader removing windrows over an average haul distance of 100 ft is 2-1/2 to 3 hr/acre.

The system can also include a screening system to separate oil-soaked debris, such as straw, from the oil-sand mixture. Applicability The use of an unloading ramp-conveyor system is dependent upon the magnitude of the beach restoration operations. In situations similar to that encountered during the Santa Barbara incident, where some 4,000 truck- loads of oil-contaminated sand and debris were hauled to disposal areas, a system of this type would have saved considerable cost and effort. Several such systems may have to be installed if oil-contamination occurs over a significant length of beach. The hauling time from the oper- ating area to the unloading area, is a factor that has to be considered in locating such a facility. The unloading ramp and conveyor-screening system illustrated in Fig. 14 can be installed for approximately $2000. A typical ramp system would consist of two cribs built out of railroad ties on each side of a hopper feeding a belt conveyor. The ramps contain approximately 100 cu yd of material, which may be found on site or brought in. A screening system can be attached to the discharge end of the conveyor system if required. Factors that would influence the design of the unloading ramp and con- veyor system are: • Conveyor capacity - estimated volume of material per hour that will be produced by beach restoration procedures • Conveyor length - height above ground required to load trucks 28 ------- to to Fig. 14. Unloading Ramp and Conveyor-Screening System ------- • Hopper capacity - hopper should have sufficient capacity to receive total load of largest elevator scraper utilized • Ramp height - depends on overall height of conveyor and hopper and depth of pit, if required • Ramp width - maximum width of largest elevating scraper utilized Table 8 lists the specifications of suitable belt loaders. 30 ------- TABLE 8 Equipment Specifications: Belt Loaders Type: Wheel, transportation required to operating site Make and Model Barber-Greene PL-90 Hewitt-Nbbins-450 Ko-Cal 4845-R Ko-Cal 4860-R Ko-Cal 4845-S Ko-Cal 4860-5 Ko-Cal 4860-S Ko-Cal 3650 Ko-Cal 4250 Kolberg 348-50 Kolberg 448-60 Kolberg 1136-50 Kolberg 1148-50 Pioneer 4841 Net Engine HP Rating 130 170 105 154 105 154 154 70 97 130 154 70 130 100 Weight including attachments (tons) 24 28.5 19 25.5 24 29 29 11.5 13 24.5 30 9.5 15 45.5 Capacity cu yds/hr 2000 2400 2800 2800 1800-2800 1800-2800 1800-2800 1200 1700 2000 2000 1000 2000 2000 Width of Belt (in.) 48 48 48 48 48 48 48 36 42 48 48 36 48 48 Labor (man hrs/hr Equipment Operator 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Requirements of equipment operations) Maintenance and Repair .26 .28 .22 .30 .22 .30 .30 .2 .22 .26 .30 .2 .26 .22 Fuel, (per hour Diesel Fuel (gal) 5.6 7.5 5.0 6.5 5.0 6.5 6.5 4.0 4.5 5.6 6.5 4.0 5.6 4.5 Oil, Lube of equip.

These rental rates do not include the cost of an operator and costs of fuel and lubricants. In addition to being national averages in dollar amounts, the rental rates reflect an averaging of age, condition and operating efficiency of the equipment. It is general practice to base rates upon one shift of 8 hr per day, 40 hr per week, or 176 hr per month of a 30-consecutive-day period. Many distributors do not rent by the day or by the week, especially in the case of large equipment. If the equipment is rented by the day, the rate for overtime is 1/8 of the daily rate for each hour in excess of 8. If it is rented by the week, the rate for overtime is 1/40 of the weekly rate for each hour in excess of 40. If it is rented by the month, the overtime rate is 1/176 of the monthly rate for each hour in excess of 176 in any one 30- consecutive-day period. Operator costs are tabulated in Table 10 for selected cities. These rates include fringe benefits. Overtime costs for operators are normally computed to be 150% to 200% of his straight-time wages. In many instances, equipment and operators will be obtained through an earthmoving contractor, and the rental rates will include equipment rental, operator costs, maintenance costs, fuel, oil, and contractor's overhead and * profit.

The tests were conducted at three beach sites along the San Mateo County, California, coastline during the month of November, 1969. Seventeen series of tests were conducted utilizing a motorgrader, motorized scrapers, and front end loaders, singly and in combination. Optimal equipment configurations, including blade angles, depth of cut, rate of operation, and necessary modifications to improve performance, were determined for each piece of equipment evaluated. The equipment evaluated included: • Motorgrader - Caterpillar Model 12, rubber tired, 12-ft blade, 115 hp • Motorized Elevating Scraper - International Harvester Model E-200, rubber tired, 9-cu-yd capacity, 135 hp, two-wheel drive. • Motorized Scraper - Caterpillar Model 10, rubber tired, 12-cu-yd capacity, 120 hp, four-wheel drive. • Front End Loader - Caterpillar Model 955, crawler tractor, 4-in-l bucket, 1-3/4-cu-yd capacity, 115 hp • Front End Loader - International Harvester Model 175B, crawler tractor, 4-in-l bucket, 2-cu-yd capacity, 120 hp The choice of make and model of equipment evaluated was determined only by equipment availability at the time of testing. These items, however, are representative of their classes, as given in Tables 2 through 7. To improve the performance on sand, the motorgrader was equipped with 23.5X25 10-ply flotation tires on all four driving wheels in place of the 37 ------- standard 13.00X24, 10-ply tires. The motorized elevating scraper was also equipped with two optional features designed to improve operating performance on sand. These consisted of the following: (a) The installation of a high-speed, low-torque motor cartridge kit to increase the elevator speed approximately 29%. (b) A transmission change consisting of a turbine and drive gear modification to reduce the ground speed from a maximum speed in first gear of 6 mph to 2.72 mph and a reduction in second gear high range from 24 mph to 16.6 mph. The operating characteristics of each piece of equipment in removing the surface layer of sand was determined at the three separate beach test sites under different beach conditions as indicated in Table 11. In several tests, oil was utilized in tidal zone areas, and in one instance on the backshore area. Also, as indicated in Table 11, in several tests the test area was covered with straw or a test area was selected that was covered with kelp and other debris. Each piece of candidate equipment was tested individually to determine its operating characteristics and performance in removing a thin surface layer of sand under various beach conditions. The motorgrader was then operated in combination with the elevating scraper and the front end loader to determine the effectiveness of combined operations. During both the individual tests and the combined equipment tests, the various pieces of heavy equipment were operated at different speeds, depths of cut, and blade angles to determine the optimum operating characteristics for equipment performance on a sandy beach. The basic test procedure was to operate the equipment on a 100- by 30-ft test area and to time and photograph the operations and obtain appropriate measurements, including width of cut, depth of cut, size of windrows and visual observations of effectiveness (i.e. amount of spillage). Finally, several tests were run to determine cycle time (i.e., a complete loading cycle, which includes loading, hauling, dumping, 38 ------- and return to loading position). In some of these tests, longer test areas were used to approximate actual conditions. For example, the scraper will normally operate in one direction and continue loading until its capacity is reached instead of making short, 100-ft passes.

Included are descriptions and locations of each beach test area, the equipment tested, the type of operation performed, detailed data on each test, including depth of cut, width of cut, length of cut, material removed, area cleaned, time of operation and cycle time (where applicable), and comments on the performance of the equipment. 39 ------- A measure of effectiveness is the amount of contaminated sand removed during a beach-restoration operation. For each operation, the volume of sand (in cubic yards) removed per acre of beach cleaned was calculated from the data tabulated in Tables 12 through 19. The results, given in Table 20 show that the smallest amount of material per acre was removed with the motor- grader and motorized elevating scraper working in combination (Restoration Procedure A, Table 1). The motorized elevating scraper operating alone was the next best procedure. The most inefficient operation utilized a front end loader to scrape up and remove the material. The range of values given are based on several tests. An important para- meter in calculating the total volume removed is the depth of cut, and in each test an average depth of cut was measured. In some instances, due to the bearing surface of the test area and topography, it was difficult for the operator to maintain a constant depth of cut. Another measure of effectiveness is the rate (acres cleared per hour) at which beach areas are cleared. Table 21 presents the rate of clearing in acres per hour for the various pieces of equipment evaluated and combinations of equipment. The calculations are based on those operations in which cycle times were taken. The values given for each equipment item and/or combination of items is based on equipment performing under optimum conditions (i.e., the motorized elevating scraper loading in first gear and hauling and returning from the dump area in second gear; the motorgrader operating in second gear for both forward and reverse; and the front end loader operating in first gear for scraping and the second gear for hauling and dumping). The calculated values are based on the haul distances given in Table 21 for each operation. Increasing or decreasing these distances would increase or decrease the rates accordingly. When a motorgrader is used in combination with a motorized elevating scraper or front end loader, the indicated rates may be increased with the use of additional scrapers or front end loaders. The motorgrader is capable of producing windrows continuously and several motorized elevating scrapers or front end loaders can be utilized to pick up and remove the windrows. 40 ------- As indicated in Table 21, the motorgrader-motorized elevating scraper combination is the most efficient for an equivalent length of haul. The least efficient is the front end loader, working singly. An example of how production decreases with increased haul distance (one-way) is shown in Fig. 15 for the motorgrader-motorized elevating scraper combination. 0 100 200 HAUL DISTANCE - one way (feet) 400 500 Fig. 15.

It was very quickly determined that there has been little to no effort directed towards the systematic collection of data needed to accurately determine the cost and effectiveness of previous beach restoration operations. Generally, only overall costs have been re- ported, and costs associated with onshore operations could not be separated from the total costs. A set of data collection sheets has been included in this annex as an example of the forms to be used by FWPCA personnel who become involved in future oil-spill incidents. As in all operations of this type, photography, both still and motion picture, proves to be invaluable during subsequent analysis of the data. Care must be taken, however, to properly document the photographic effort, i.e., date, time, location; etc. A sketch or quadrangle map showing beach location and important features, such as breakwaters, groins, roads, and other shoreline installations, would assist in subsequent analysis of the cleanup operation. 51 ------- BEACH RESTORATION PROCEDURES DATA SHEET INSTRUCTIONS Separate data sheets should be prepared for each separate event, type of beach, variation of beach characteristic, or restoration procedure. If it is necessary to use more room for entries than that provided on the sheet, use the reverse side of the form. Identify each separate page by including beach name, its location, and the data at the top. Section A: Event description - include what spilled, from where, what caused spill (collision, explosion, grounding, pipeline failure). Section B: This information is pertinent for prediction of weathering effect on contaminant. Section C: Data in this section will be utilized to assist in the evaluation of the cost and effectiveness of the beach restoration operation and to correlate trafficability (mobility) factors with equipment type. Sand samples should be taken in both the tidal and back- beach zones for sand grain size determination. If it is necessary to clarify data or obtain additional information, the persons reporting or submitting the data forms will be contacted. Section D: This section is to be used for equipment actually cleaning the beach and does not include hauling operations. A daily estimate of area cleaned and cost should be recorded. Participating organizations would include the names of agencies, (FWPCA, API); companies (oil companies, private research or con- sulting firms); contracting firms; local and state authorities which were directly involved in clean-up procedures. The organiza- tions should be listed, where applicable, across the top of the daily record squares. If equipment is under contract, rented or leased, it should be shown as a note under Comments, Observations. If certain equipment is immobilized by a low-bearing beach, this should also be noted. Record all information possible; although, partial reporting of data may be all that is available. Section E: Hauling operations, exclusive of beach cleanup, should be included here. If contaminated sand and debris are hauled to several dis- posal areas, include specific details on reverse side of form. 52 ------- Participating organizations would include the names of agencies, (FWPCA, API); companies, (oil companies, private research or consulting firms); contracting firms; local and state authorities which were directly involved in sand disposal operations. The organizations should be listed, where applicable, across the top of the daily record squares. Section F: If a change in type of absorbent, or dispersal methods occurs during the seven days covered by these sheets, but all else remains relatively unchanged, write additional information on reverse of form. 53 ------- Page 1 of 5 BEACH RESTORATION PROCEDURES BEACH'.
