I don't understand why comparing strings is not working here:

while IFS=, read -r ELMS_SIZE ELMS_NAME ELMS_ENV ELMS_DB
do

if [ "${ELMS_DB}" = "NOMATCH" ]; then
 echo "done"
fi

done < <(tac ${CSM_DATA_DIR}/test.csv)

exit

ELMS_DB has string value of NOMATCH, example of output for test.csv

12 am_pltconfig9 unknown NOMATCH
12 am_pltconfig8 unknown NOMATCH
12 am_pltconfig7 unknown NOMATCH
12 am_pltconfig6 unknown NOMATCH

Based on your example of test.csv, your file is not actually comma separated but space separated instead. Try changing your while read loop to:

while read -r ELMS_SIZE ELMS_NAME ELMS_ENV ELMS_DB
do
  if [ "$ELMS_DB" = "NOMATCH" ]; then
   echo "done"
  fi
done < <(tac "${CSM_DATA_DIR}/test.csv")

exit
