Narrative:

During the takeoff roll, the left 'environmental fail' warning light illuminated. As I had briefed, we aborted the takeoff. After clearing the runway and notifying ATC, we ran the rejected takeoff checklist, then the 'environmental fail' checklist. This checklist told us to recycle the affected bleed air control. This resulted in the annunciator being extinguished. The checklist stated that if the light extinguished to continue flight. I mistakenly assumed this meant that no further action was required and advised tower that we were ready to depart. I did not discover my error until later on that day when I checked our flight operations manual with regard to filing a pilot irregularity report with the company. At this time I realized that I had not contacted operations to amend my dispatch release. I proceeded to contact the chief pilot and he advised me to file this report. I feel that the greatest factor in this incident is my inexperience. I acted as a first officer on this aircraft with this company for 8 months and acquired 427 hours prior to my upgrade to captain. After training, I completed approximately 27 hours of IOE and approximately 30 hours of line flying during which I had never actually aborted the takeoff. I was under the misunderstanding that if the abort did not require a maintenance action and was still within the valid time, there was no amendment required to the release. I am now aware of exactly what is required after an abort and/or air return.
