<br /> • Abandon monitoring wells MW-1 through MW-20 in accordance with applicable regulations
<br /> as part of the site closure preparations, AGE will contact the consultants for New West
<br /> Petroleum to discuss the possibility of transferring responsibility of certain monitoring wells
<br /> (i e MW-8,MW-10,MW-19 and MW-20)that could still be utilized for their investigation
<br /> 10.0. LIMITATIONS
<br /> Our professional services were performed using that degree of care and skill ordinarily exercised by
<br /> environmental consultants practicing in this or similar localities The findings were based mainly
<br /> upon analytical results provided by an independent laboratory Evaluations of the
<br /> geologic/liydrogeologic conditions at the site for the purpose of this investigation were made from
<br /> a limited number of available data points (i a ground water samples, soil-vapor samples, soil
<br /> samples, CPT data), and subsurface conditions may vary away from these data points No other
<br /> warranty, expressed or implied, is made as to the professional recommendations contained in this
