13 DULANEY HIGH SCHOOL FEASIBILITY STUDY APPENDIX E: FOOD SERVICE MEMO A. GENERAL DESCRIPTION: Dulaney High School kitchen operates as a full-service/production facility equipped to produce meals for the students and staff of Dulaney High as well as three feeder elementary schools. Dulaney High School opened in 1964, which is when the two of the three existing serving lines were installed. Much of the equipment, although well maintained, is old, outdated, insufficient, non-compliant with current codes and has seen its useful life. The kitchen had a minor renovation in 2001 which included the addition of a four-compartment pot washing sink, the installation of a walk-in freezer and the replacement of the kitchen hood. B. EXISTING CONDITIONS: 1. FINISHES Floors. Kitchen and main serving area are thick-set quarry tile. The floor has been maintained; however, due to smooth surfaces, tiles can be very slippery when wet or laden with grease. Walls. The walls in the serving line area and kitchen are covered by a 4 x6 ceramic tile and appear to be well maintained. There are six individual doors leading from the cafeteria into the serving area. A row of large ribbon windows extends above the tiling on this wall. Ceilings. High, painted ceilings extend through the serving are and kitchen. Lighting. Lighting in the serving area is 2 x4 recessed fluorescence. Most of the kitchen has 1 x4 surface mounted lights; however, a portion has 1 x4 recessed lights. Overall, the lighting levels are poor. 2. AREAS Dry Storage. Dry Storage is a small room with items stored on perimeter shelving; however, the room does not appear to be over packed. The ceilings are painted drywall. The walls are the covered with the same ceramic tiles as the kitchen and serving area and the floor is quarry tile. Walk-in Coolers and Freezer Storage. The freezer was installed in 2001, has a diamond plated floor and appears to be in good condition. There is adequate space in the freezer. The cooler, acquired in 1993 is small, crowded and needs attention, including the concrete floor which needs to be repainted. The refrigeration system for the cooler was replaced in Baltimore County Public Schools Food Service Memo-Appendix E Page 1 Office of Engineering and Construction February 18, 2016 Dulaney High School Feasibility Study

14 Kitchen. The kitchen is an interior space, which lacks windows and air conditioning and gets hot during the warmer months. A new HVAC system should be installed to control the temperatures in the winter and provide air conditioning in the summer to temper the space to avoid overheating the area. The cooking equipment in the kitchen does not match the menu and should be reevaluated to include the proper equipment. Serving. The serving line area consists of three serving lines. These serving lines are original. Two of these lines are single construction units. Several of the components of this equipment has failed and is no longer functional, included the ice cream coolers and milk coolers. In 1996, these lines were modified to add two drop-in-cold wells for milk. The third line is thrown together to form a make-shift serving line. This area should be redesigned to provide U-shaped serving lines with individual pieces of equipment, matching BCPS current standards. This would provide better service and less wasted space by components which no longer function. Dishwashing. BCPS uses all-disposable dinnerware. Area contains a four-compartment pot washing sink and shelving to store pots and pans. Janitor Closet. The kitchen has two rooms, on opposite sides of the kitchen. There is a narrow room which holds the mops, buckets and a shelf. The second room is small and has a wall mounted custodial sink and should be replaced by a floor mounted mop sink. Receiving. A double door with screen leads out the back of the kitchen to a hallway accessible by both staff and students. Workers must pass turn the corner to reach a receiving room. This area has a large coiling metal door which is manually operated and exits to the loading dock. Also in this area, is a paper storage room which holds cups, napkins and lunch trays.

15 3. EQUIPMENT Exhaust Hood. This is the original exhaust hood from 1961 and should to be replaced. Current Cooking Equipment. 1) (2) Double-Deck Convection Oven (1996 & 2010) 2) (2) Steam Kettle (2001) 3) (1) Double-Deck Steamer (1972) The 1972 steamer should be replaced and one of the steam kettles should be removed and replaced with an additional double-deck steamer. Serving Counters. The serving equipment is original and is single construction. Several components are non-functioning; however cannot be removed as they are all integrated together. This equipment should be replaced. Worktables, Prep Sinks, Pot Sinks. Many of the worktables and prep tables are the original equipment and should be replaced. C. CONCLUSION: Although large in space, rooms are scattered throughout the kitchen making it labor-intensive to perform the work required. Also, despite that some systems have been updated, the kitchen would greatly benefit from a renovation to reorganize the available space to bring order to the kitchen. Additionally, the serving line equipment should be redesigned to provide a better functioning area to better serve the students and the employees that serve the food.

35 I. INTRODUCTION Arc Environmental, Inc performed an Asbestos Hazard Emergency Response Act (AHERA) three-year reinspection for Baltimore County Public Schools (BCPS) at Dulaney High School in compliance with 40 CFR Part 763. The school property is located at 255 Padonia Road in Baltimore, Maryland. The inspection was conducted in accordance with AHERA requirements for asbestos-containing building materials (ACBMs). Mr. Joe G. Lewis III, an EPA-accredited Asbestos Inspector, conducted the re-inspections on July 20 and 21, Prior to the re-inspection, previous reports, abatement records, and sampling data were reviewed. 3

36 II. INSPECTION A. Scope of Work The purpose of the re-inspection was to assess the conditions of previously identified ACBMs and assumed ACBMs within the building interior. The re-inspection was nondestructive and limited to only accessible areas throughout the building. Inaccessible areas were documented and are identified in this report. It should be noted that inaccessible areas include, but are not limited to, wall cavities, pipe chases, and areas above fixed ceiling systems (i.e. plaster, sheetrock, splinted tile). The scope of work performed during the three-year AHERA re-inspections and by the EPA-accredited Asbestos Inspector is summarized below: 1. Visually inspected and assessed the conditions of all known friable and/or assumed ACBMs; 2. Visually inspected and touched materials that were previously considered non-friable ACBM to determine whether it had become friable since the last inspection or re-inspection; 3. Identified all homogeneous areas and materials that had become friable since the previous inspection or re-inspection; 4. Collected bulk samples (as approved by BCPS) for each homogeneous area of newly friable material assumed to be ACBM, and submitted suspect materials for laboratory analysis; and 5. Assessed the condition of newly friable materials in the areas where samples were collected, and in areas where materials are assumed to be ACBM. B. Process of Inspection To determine the various types and locations of ACBMs, Arc Environmental, Inc. reviewed original management plans, abatement records, and re-inspection reports, as well as, any other relevant sampling or survey data for the school building. Information collected during the re-inspection was recorded on asbestos inspection forms, and included room identification, homogeneous area numbers, ACBM description, ACBM AHERA classification, total quantities observed, and sample information from previous re-inspection reports. Previous inspection reports were utilized to reconcile the location of materials that are identified as asbestos-containing and/or are assumed to be asbestos-containing. In instances where new materials were observed, unique homogeneous area numbers and material descriptions were generated by onsite personnel. Based on observations, a total of four (4) additional homogenous areas of suspect materials were identified during the re-inspection. The additional homogeneous area numbers and corresponding material descriptions are provided below: BG1 Boiler Gasket TR1 Transite Sink TR2 Transite Fume Hood VB2 Brown Black Vinyl Baseboard and Mastic 4

37 As part of this inspection, ACBMs were visually assessed to determine their condition. The EPA has formulated a seven (7) category numerical assessment code depending on the type and condition of ACBM as follows: 1. Damaged or significantly damaged thermal system insulation asbestos-containing material (ACM); 2. Damaged friable surfacing ACM; 3. Significantly damaged friable surfacing ACM; 4. Damaged or significantly damaged friable miscellaneous ACM; 5. ACBM with potential for damage; 6. ACBM with potential for significant damage; and 7. Other or any remaining friable ACM or friable suspected ACBM. ACBMs were re-inspected and categorized within one of these assessment codes. Following the assessment and review of assessment data, response actions were developed for each material. With regards to controlling asbestos in buildings, the EPA defines response action as removal, repair, encapsulation, enclosure, and operations and maintenance (O&M) program. The following is a brief description of each response action: Removal removing the ACBM from the building. If performed properly, the hazards associated with disturbance and subsequent exposure from the material is eliminated. Enclosure Airtight, impermeable, permanent barrier constructed around an ACBM; an enclosure is only effective if it remains undamaged. Encapsulation Treatment of an ACBM with a material that surrounds or embeds the material with an adhesive matrix to prevent the release of fibers. The encapsulant creates a membrane over the surface of the material (bridging encapsulant) or penetrates and binds material components together (penetrating encapsulant). Repair returning damaged ACBM to an undamaged condition or an intact state so as to prevent a fiber release; if an ACBM has become damaged, the damage should be repaired immediately. Operations and Maintenance (O&M) Program Work practices developed to maintain ACBM in good condition, ensure the clean-p of asbestos fibers previously released, and to prevent further release by minimizing and controlling ACBM disturbances or damage. The O&M Program must be implemented until all of the asbestos-containing material is removed from the facility. It should be noted that for all response actions, with the exception of removal, the hazardous material remains in the building and must be monitored periodically. Warning labels should be attached immediately adjacent to any friable and non-friable ACBM and suspected ACBM assumed to be ACM located in routine maintenance areas at the school. C. Data Gap Analysis Previous inspection reports, as well as sampling data from demolition surveys and various abatement projects were utilized to reconcile materials that are identified as asbestos-containing and/or are assumed to be asbestos-containing. Through these efforts, a number of materials have been removed from the presumed ACBMs identified in previous reports. 5

38 Surfacing Plaster Ceiling and Wall Finishes In November of 2011, Advanced Air Analysis, Inc. (AAA) conducted a plaster and drywall survey to determine the asbestos content of suspect materials. During the survey, AAA collected bulk samples of various plaster finishes from randomly selected locations throughout the school building. A total of thirtyone (31) bulk samples were collected and submitted for laboratory analysis by Polarized Light Microscopy (PLM) and Transmission Electron Microscopy (TEM). Laboratory analysis indicated that the skim coat layer of acoustical plaster is asbestos-containing. The asbestos-containing acoustical plaster appears to be restricted to ceiling finishes within the auditorium and auditorium lobby. Based on the review of previous inspection reports and available sampling data, the remaining plaster located throughout the school building does not contain asbestos. Miscellaneous Drywall Wall and Joint Compound During the plaster and drywall survey conducted by AAA in November of 2011, total of twelve (12) bulk samples of drywall and joint compound were collected and analyzed by PLM and TEM microscopy. Based on the laboratory analysis, the drywall remaining in the school building does not contain asbestos. Ceiling Tile In March of 2011, AAA performed a survey throughout the building to determine if any asbestos-containing ceiling tiles were present. AAA identified seven (7) types of ceiling tile differentiated by size, color, and texture. A total of twenty-seven (27) bulk samples were collected and submitted for laboratory analysis via PLM and TEM analysis. Laboratory analysis indicated that none of the sampled ceiling tile contained asbestos. Tectum Board In February 2001, KCI Technologies, Inc. (KCI) performed a hazardous materials survey as part of renovation to the science laboratories within the school. During the survey, multiple samples of Tectum board were collected from the ceiling plenum of each renovation space and submitted for laboratory analysis via PLM and TEM. Based on the laboratory analysis, the Tectum board within the school does not contain asbestos. D. Results An effort was made to locate and assess the rooms listed below; however, visual confirmation was not acquired before the issuance of this report. All remaining portions of the building were included in the inspections. The following locations could not be surveyed: 6

39 Following the review of previous inspection reports, abatement records, and sampling data, a total of fiftythree (53) homogenous materials are considered asbestos-containing at Dulaney High School. Thermal System Insulation Four (4) materials were identified and categorized as Thermal System Insulation (TSI) during the reinspection. These materials include mudded pipe fittings, pipe insulation, duct insulation, and breeching insulation. Sample data from previous inspection indicated that the mudded pipe fittings with the school are asbestos-containing, all remaining TSI is assumed to be asbestos-containing. Miscellaneous Floor Tiles and Associated Mastics Both asbestos-containing and assumed asbestos-containing floor tiles were identified within the school building. Floor tiles that have not been sampled are assumed as asbestos-containing materials until negated through bulk sampling and laboratory analysis. Fire Doors, Sink Undercoating, and Vibration Dampener Cloth Fire doors, sink undercoatings, and vibration dampening cloth were identified throughout the school building during the inspection. Due to the destructive nature of sampling, and the potential to negatively impact the integrity and/or function, these materials are assumed to be asbestos-containing. Adhesive and Mastics Various adhesives utilized for hanging materials such as chalkboards were identified throughout the building. The adhesives and mastics utilized within the school are assumed to be asbestos-containing. Transite Panels, Sinks, Window Sills, and Thresholds Transite materials were identified throughout the school building. Sample data from previous hazardous materials surveys indicate that several of these products, including fume hoods, contain Chrysotile asbestos. All transite materials are assumed to be asbestos-containing. Table I below identifies the locations and quantities of ACMs within the building, and summarizes information regarding sample history. 7
