The main building was report- ed to have been occupied by a homeless popula- tion for many years. Since 1993, the main build Ing was listed in the National Register of Historl- cal Resources, and categorized as a "Landmark" because it "is on the national register," "is on the state register", "has htstorlcal/cultural signifl- dance for the City of Santa Ana," and „has a unique architectural ,significance". The City of Santa Ana owned the structures and was entertaining the idea of selling the buildings. A hazardous pact AGMs, lead containing surfaces, universal wastes, and birdlrodent and human waste were present throughout most areae of the main building, Buildings on the property include: Main Building, a three-story structure including a basement which occupies an approximate 44,460 -square foot (SF) area; Southwest _Building,a single-sftnrystructore which occupies an approximate 1,2007 $F 8r - ea; Concrete Block Building, a single -story structure which occupies an approximate 750 -SF area; and Handball Courts, a single -story structure which occupies an approximate 2,000 -SF area The HRMS includeda review of existing hazardous building material related documents for titie site provided by the City of Santa Aria; performing an asbestos survey, a lead survey, and performing a visual evaluation for the presence of Universal Waste Rule hazardous materials including potential mercury -containing thermostats, switches, and fluorescent light tubes; items potentially containing PCBs; potential tritium or baftery-containing exit signs; and "potential Chlorofluorocarbon -contain ing refrigeration systems (in accordance with current standards and practices); and deliverable reporting of the HBMS activities. Based on the results of the HBMS, Ninyo & Moore, working veryclosely with the City of Santa Aria, participated in the job pre-bid walk, responded to request for clarification from contractors, and pre- pared abatement bidding specifications for removal of hazardous building materials (asbestos, lead, universal, and other wastes). The specifications provided guidelines and instructions for the general and abatement contractors to follow for the handling of asbestos, leadcontainingmaterials, and miscellaneous hazardous building materials located within the site structures. Because of the exten- sive damage of the structures, a SCAQMD Procedure, 5 Flan was needed and prepared by Nlnyo Moore. The abatement specifications also needed to be mindful of the historical preservation needs of the structures. N?inya & Moore performed the hazardous materials abatement monitoring services over a four-month period. Upon recolpt of documentation from the abatement contractor, Ninyo & Moore prepared the hazardous abatement closeout report, which summarized the abatement activities, air monitoring data, and clearances, Ninyo & Moore I Oily of Santa Ana- (Q) Iiaznrdous Material SurVeys 105-00713 A2 i dune 5, 2018
