ArcInfo encompasses ArcView and ArcEditor but performs with more refined tools, and advanced analyses. GBK can collect, collate and analyze data and create professional maps for our clients. In the past we have used ArcInfo to help us with the creation hundreds of new and specialized maps.

Among the many maps GBK has created, these are just a snapshot of our skills:

• Perform geographic queries
• Process and convert vector and raster data
• Create topographic maps
• Create viewshed maps
• Create 3-D and/or animated maps
• Create coordinate geometry maps that are able to re-create features surveyors have captured
• Create maps that represent surface morphology
• Digitize using aerial imagery

Spill Prevention Control and Countermeasures Plan Update

Fort Sill EQD, Fort Sill, OK

Under the Federal Water Pollution Control Act (regulations found in 40 CFR part 112) facilities subject to the SPCC rule must prepare a plan to prevent the release of oil to the navigable waters of the United States. GBK, in partnership with CH Guernsey & Co., completed a review and update of the Fort Sill Spill Prevention Control and Countermeasures Plan (SPCCP) and the Installation Spill Contingency Plan (ISCP). The update included assessing approximately 70 individual industrial-style facilities for inclusion in the plan. GBK performed the mapping component of this project. Each facility was mapped byArcInfo from available aerial imagery and information recorded from site visits. Facility diagrams included all pertinent information such as all outside-of-building hazardous materials and oil storage locations over 55 gallons, tanker pads, spill kits, oil-water separators, storm drains, direction of flow and unpaved ground. Locations of spill kits, fire hydrants and secondary containments were also recorded. Data during site visits was recorded using a Trimble GeoXT GPS handheld with submeter accuracy and uploaded to the GIS server. The facility descriptions included calculation and analysis of the adequacy of available secondary containment for a worst-case discharge scenario during a 25yr storm event. Where applicable, the acceptable environmental equivalence was detailed or the facility was flagged for further action. Furthermore, the Installation Spill Contingency Plan was updated and brought into line with requirement.

Some milestones and deliverables included:

1. Inspected and assessed 70 facilities subject to the SPCC Rule;
2. Facility maps generated using ArcInfo through a combination of aerial imagery digitization and field data analysis.
3. All maps were produced in full color, customized to the clients requirements and reproduced in appropriate formats for the plans ;
4. Delivered SPCC plan and ISCP prior to July 2009 new revision deadline extension required by USEPA and in time for installation EPAS inspection.
