Attached is the routine monitoring program which was developed by Jackie Gaul and Steve Paul during the week of April 11, 1983. This program represents the minimum requirements to maintain a quality, sustaining plant routine monitoring effort. The program does not include special monitoring (e.g., start-up, turn-around, special request, etc.). Monitoring requirements need to be reviewed annually and adjusted where appropriate to be commensurate with monitoring results and good IH monitoring strategy.
Routine monitoring is a basic element of a plant industrial hygiene program. It encompasses the means of recognizing health concerns. Our ability to evaluate or control occupational health exposures requires quality monitoring data. To effectively target resources to such downstream programs as hearing conservation, respiratory protection, training, personal protective equipment, etc. also requires accurate assessment of worker exposure to workplace stresses.
The monitoring assessment also affords an opportunity to review equipment and manpower resources generally to determine if a quality routine monitoring program can be executed. There are no significant problems in this respect at Chocolate Bayou.
The routine monitoring program developed has the ability to evaluate health hazards, control methods, periodic monitoring results, and compliance with regulatory requirements. It will provide you with quality data from which you may make IH and business decisions. The program should define maximum worker exposure taking into account such variables as seasonal exposure, shift exposure (i.e., day vs. evening vs. graveyard), and job exposure ranges.
Monitoring requirements reflect the nature of the substance/agent of concern, its use in the Chocolate Bayou Plant, and associated regulatory requirements. For example, a substance with a TWA type standard will require TWA type monitoring to document expo sures, whereas substances with TWA/STEL or ceiling standards require a different monitoring strategy to ensure adequate expo sure documentation. Noise monitoring is specifically designed to effectively quantify exposures of all noise exposed job classifications. This provides you with a means of defining the worker population affected by the Monsanto and OSHA hearing conservation programs.

Monitoring will require lab and field validation to ensure data quality. Multicomponent analyses will require multicomponent validation either by single injection of multicomponent standards or multiple injections of single component standards.
All routine monitoring forms should be retained at the plant and all monitoring data should be entered into the OE Subsystem of MEHI to assist in data evaluation and recordkeeping.
The table below summarizes the plant monitoring programs for 1981 and 1982 and compares them with the developed routine monitoring program for 1983.
Criteria

Note the following results of the monitoring assessment conducted.
An increase in the number of substances/agents of health concern monitored
An increase in assessing agents of concern without monitoring
A decrease in the overall number of analytical results needed
Total annual samples required remains approximately the same
A decrease in the overall cost of the routine monitoring program
Since exposures at Chocolate Bayou are very low in the vast majority of cases, the strategy is to look at a wider variety of agents to ensure worker health protection, but use less samples so long as results remain low. Routine monitoring includes agents assessed several years ago by the plant, but not monitored in the past 3 years. Overall program cost can be further reduced by developing multicomponent analyses for some of the materials which are being introduced in 1983.
Also attached is a detailed breakdown of routine monitoring by unit and a list of substances/agents which should be monitored. If there are questions, please contact me.
