environmental engineering


Gerald Spencer, PE is the Engineer of Record responsible for the design and the construction of several environmental related systems to comply with EPA regulations.

1.   ENVIRONMENTAL ENGINEERING: We do not have in-house environmental assessment capability. We utilize consultants when

environmental assessment capability is a part of our required services.

We provide we provide the engineering design of systems and plants when required to implement the recommendations made by NASA, US Army, USAF, or separate environmental engineering consultant firms. 

These projects include aircraft wash rack water/oil separators, slip-lining sanitary sewers to minimize exfiltration, plants for ground water removal of contaminants, hazardous waste storage facilities, and underground storage tanks for hazardous waste.  Completed EPA projects where Gerald R. Spencer, P.E. is the Engineer of Record for the design and the construction are as follows:

1.1.    NASA-JSC, abrasive blast area TNRCC site definition & testing

1.2.    NASA-JSC, thermochemical test area site hydrazine control and remediation

1.3.   NASA-JSC, thermochemical test area groundwater freon contamination remediation

1.4.   NASA-JSC, hazardous material holding tank facility certifications

1.5.   NASA-Ellington AFB, open air aircraft wash rack with oil/water separator

1.6.   U. S. Army Reserve Center, Amarillo, TX, open area equipment wash rack

1.7.   U. S. Army Reserve Center, Marshall, TX, open area equipment wash rack

1.8.  U. S. Army Ammunition Plant, Karnack, TX, diked covered storage

1.9.   U. S. Army Ammunition Plant, Karnack, TX, hazardous waste storage trailer facility


2.  LABORATORY AND RESEARCH FACILITIES: Gerald Spencer, PE is the AE of record  and the EOR for the design and the construction of the HVAC systems for many medical research laboratories where bio-safety is the primary design concern.  Projects include the M D Anderson Surgical Research Laboratory, NASA Lunar Receiving Laboratory, The Methodist Hematology Research Laboratory, The Methodist Hospital Immunology Research Laboratory, Fort Sam Houston Institute of Surgical Research, and The Methodist Hospital Brown Building.  This includes more than 30 petrochemical research laboratories, and more than 20 bio-safety medical analytical laboratories.


3. HAZARDOUS WASTE OPERATING PERMITS:  Gerald Spencer, PE is the AE of record for the NASA-JSC Class 2 hazardous waste operating  permit application to the TNRCC (Texas Natural Resources Conservation Commission) for the construction and operation of the central hazardous waste collection facility.  The operating permit was granted.


4.   GROUNDWATER CONTAMINATION REMOVAL:  Gerald Spencer, PE is the AE of record for the NASA-JSC aeration plant for removal of VOC (Freon and Hydrazine) groundwater contaminants in the aquifer.  The aquifer was contaminated with Freon used for cleaning Hydrocarbons from space craft propulsion parts.


5.  UNDERGROUND HAZARDOUS STORAGE TANK CERTIFICATION:  Gerald Spencer, PE has designed and certified several underground hazardous collectionpiping systems and underground storage tank installations to be in compliance with EPA requirements at NASA-JSC.  This included all leak detection and alarm systems.


6.  ASBESTOS  ABATEMENT: EFI, Inc.  and Geo-Marine, Inc. can survey for asbestos and prepare contract documents for the abatement of asbestos if found.  EFI, Inc. and Geo-Marine, Inc. have laboratories to analyze samples of any suspect material.   Gerald Spencer, PE is been the AE of record for multiple asbestos abatement projects during the past 25 years.  Gerald Spencer, PE has surveyed facilities to discover and define the location of asbestos materials used in the original construction.  We have multiple project experience preparing drawings and writing specifications for removal procedures with methods of testing and sampling that are required for competitive bidding of asbestos removal, abatement, and disposal.  We are familiar with OSHA and EPA requirements.  When testing and sampling are required, we call on EFI and Geo-Marine, Inc. as consultants for asbestos survey and abatement design.


7.  LEAD BASED PAINT ABATEMENT: We use Lead Based Paint Detection Corp. (LBP) as consultants for lead based paint lead content detection.  They know the latest regulations and guidelines pertaining to lead hazard reduction.  They use portable X-ray fluorescence (XRF) paint analyzers to test the existing paint for lead.  LBP is currently performing lead based paint survey and abatement services at Lackland AFB, TX as our consultant.  Gerald Spencer, PE has been the AE of record for multiple chlordane risk reduction projects during the past 10 years.  Gerald Spencer, PE has surveyed  facilities to discover and define the location of lead based paint used in the original construction.  Gerald Spencer, PE has multiple project experience preparing drawings and writing specifications for chlordane risk reduction procedures with methods of testing and sampling that are required for competitive bidding of lead based paint abatement and risk reduction.  We are familiar with OSHA and EPA requirements.


8.  CHLORODANE RISK REDUCTION: EFI, Inc., ENSR, and Geo-Marine, Inc. can survey for chlordane and prepare contract documents for the risk reduction of chlordane if found.  EFI, Inc., ENSR, and Geo-Marine, Inc. has laboratories to analyze samples of any material suspected of containing chlordane.   Gerald Spencer, PE has been the AE of record for multiple chlordane risk reduction projects during the past 10 years.  Gerald Spencer, PE  has surveyed facilities to discover and define the location of chlordane containing material used in the original construction.   Gerald Spencer, PE has multiple project experience preparing drawings and writing specifications for chlordane risk reduction procedures with methods of testing and sampling that are required for competitive bidding of chlordane risk reduction projects.  We are familiar with OSHA and EPA requirements.  When testing and sampling are required, we call on our consultants for chlordane survey and abatement design.  We have used ENSR to perform chlordane survey and abatement services at Lackland AFB, TX as our consultant.


9.   PCB SURVEY & REMOVAL: ENSR,  Inc. can survey electrical equipment for PCB content and prepare contract documents for the removal of PCB if found.  ENSR, Inc. has laboratories to analyze samples of any material suspected of containing PCB.   Gerald Spencer, PE has been  the AE of record for several PCB removal projects during the past 10 years.  Gerald Spencer, PE has surveyed facilities to discover and define the location of PCB  containing electrical equipment used in the original construction.    Gerald Spencer, PE has multiple project experience preparing drawings and writing specifications for PCB removal procedures with methods of testing and sampling that are required for competitive bidding of PCB removal projects.  We are familiar with OSHA and EPA requirements.  When testing and sampling are required, we call on ENSR as our consultants for chlordane survey and abatement design.   We have used ENSR to perform PCB detection survey and removal services at Lackland AFB, TX.
