Edition. Biographic Sketch, Professional Responsibilities, and Contributions to Technical Field:

I served as a member of the [CH2M HILL, Inc.] Southeast Region in Florida and Alabama, and as a member of the Global Wastewater Service Team (under the supervision of the Director of Technology) who was responsible for guiding wastewater treatment technological endeavors including first of their kind wastewater treatment (a.k.a. water resource recovery) plant process designs, externally and client funded applied research and development projects, program management exceeding one billion dollars, the development and application of internal tools such as proprietary wastewater treatment plant simulators and parametric cost estimating software to name only a couple that serve to create a standard for practice and quality control across an enterprise which consisted of approximately 40,000 employees internationally. My next professional appointment was as the Wastewater Technology Leader for Stantec, Inc. My responsibilities for Stantec, Inc., under general direction of the Water Technology Director, included supervision of related technical staff and project delivery of wastewater infrastructure projects throughout North America. I was also responsible for coordination with regional managers to ensure funding/resource allocation and business development across the Water Division. I was also expected to provide a technical platform for quality control, project delivery, and the use of technology to create business opportunities. I was the Stantec, Inc. chief wastewater treatment process modeler, and committed to the planning and design of municipal and industrial wastewater projects. My appointments required the management of training and marketing opportunities by identifying who would attend State, National, and International conferences to ensure clients, competitors, and the academic community were exposed to our leadership role with respect to emerging technologies – particularly environmental biotechnologies that can help clients meet effluent water quality standards in a cost effective manner while simultaneously addressing emerging environmental concerns such as green house gas emissions,

Boltz C.V. - 15

micropollutants, sustainable wastewater treatment, source separation, water reclamation, and resource recovery during the next 10 to 20 years. In addition to these emerging environmental concerns facing the water quality environment, rapidly aging infrastructure and a rapidly depleting work force has created a pipeline problem (i.e., the attrition of experienced engineers, operators, inspectors, and contractors at a rate that exceeds the industry’s capacity to replenish and train replacement talent). Unprecedented challenges facing the water quality environment has created unique business opportunities that will allot a properly motivated and prepared engineering firm that is equipped with the human resources required to capitalize on a forthcoming period of substantial project build-up resulting from delinquency in the repair and rehabilitation of equipment and unit processes since the recession began during 2008. In addition, the inevitable implementation of more stringent effluent water quality standards and wet-weather flow management are some of the drivers that will lead to a prolonged period of wastewater collection, conveyance, treatment, and discharge (pumping) facilities construction: greenfield, repair, and rehabilitation. The following bulleted list summarizes municipal wastewater treatment plant design activities I performed to maintain water quality ranging from basic wastewater treatment plant improvements to the execution of unique technological solutions whose projects have positioned the firm(s) I worked for to be global technological leaders in the respective field of wastewater treatment regarding focused environmental biotechnologies such as moving bed biofilm reactors, integrated fixed-film activated sludge, intentional struvite precipitation, partial nitrification and deammonification (via anammox), and granular sludge technologies. These activities include:

raw sewage screening unit design and construction oversight PISTA-type grit removal, washing, and conveyance facilities, circular and rectangular primary clarifiers (with CEPT if employed), biological wastewater treatment process design including process evaluation and

selection, bioreactor configuration/zoning and respective volumes, and internal mixed liquor recirculation pumping facilities capacity and configuration,

business development and project team management. responsible charge for maintaining a database describing the firm’s history with

specific technology types, for example, biofilm reactor types including trickling filters (TFs), trickling filter/solids contact (TF/SC) processes, rotating biological contactors (RBCs), fluidized bed biofilm reactors (FBBRs), biologically active filters (BAFs), moving bed biofilm reactors (MBBRs), integrated fixed-film activated sludge (IFAS) processes meeting treatment objectives ranging from nitrification to enhanced biological nutrient removal, and emerging biotechnologies such as granular sludge and membrane biofilm reactors (MBfR). The database must list key team members, client name and contact information, catalog system that can point the interested party to conformed documents, specifications, submittals, and related projects.

In addition to facilitating business development, take responsible charge for mentoring staff in wastewater process engineering and

wastewater treatment plant design. If the junior engineer has an interest of high predisposition for a particular environmental biotechnology or design facet, then facilitate and nurture this interest. If the interest is not a particular strength of myself, then identify an engineer or scientist who is particularly string in this area and promote collaboration between the mentor and mentee. The mentor-mentee relationship is one of a company’s strongest tools for keeping staff happy and motivated, promoting a positive working environment, promoting recruitment via word of mouth, and creating a pipeline that directs the finest young talent to our firm.

Bed expansion (~50% packed bed height) rather than fluidization (> 100% packed bed height) and the fact that the coke has a lower unit weight than sand was proposed to reduce energy cost (for recirculation pumping) and pure oxygen is used as the electron acceptor rather than air to reduce physical foot print.

Project. Senior reviewer for final design and construction documents Nitrogen control plan Each phase of wastewater treatment plant planning has been performed as a portion of this $1.2 billion dollar capital improvements program and its management (including program planning, master planning, project definition, and basis of design preparation) for the upgrade to the South WWTP. The expanded and improved WWTP will have a hydraulic capacity of 363 mgd and base treatment capacity of 58 mgd. Process components include raw-sewage equalization (60 MG), new raw-sewage pumping and preliminary treatment including screening and grit removal, improvements to the existing primary treatment system in the form of chemically enhanced primary treatment, trickling filter/solids contact (with snail shell control), flocculator clarifiers (with chemical enhancement), RAS/WAS pumping stations, expanded disinfection (ultraviolet), expanded effluent pumping, improved and expanded gravity and gravity belt sludge thickening, sludge blending tanks, improved anaerobic digestion, and expanded sludge dewatering with belt filter press units.

24. Olympia Complex MBBR Operations Assistance, Exxon Corporation, Yuzhno Sakhalinsk, Russia. Optimization and trouble shooting of a four-stage MBBR preceded by chemically enhanced primary treatment (CEPT). The system was supposed to nitrify cold wastewater, but the process was inhibited by copper toxicity. A combination of empirical criteria and a rigorous mathematical modeling study was applied to evaluate the potential for macronutrient limitations (specifically the macronutrient phosphorus) tools and system over loading. Operational recommendations were made that have restored nitrification and established an actual treatment capacity for their MBBR.
