Emergency overflow provisions fora Qioo would also be installed. <br />Regular maintenance (visual monitoring and cleaning) will be performed by the <br />' Operator as required to maintain a functional facility. <br />The preliminary sizing of the facility has resulted In a surface area oP <br />' approximately 75' by 150' at 6' deep.

INTRODUCTION: The following plan specifically addresses revegetation <br />and related aspects of the surface treatment oP the disturbances along <br />the Snyder Quarry Road. This portion of the corrective action Flan <br />addresses the nature and placement of plant growth media and the <br />' revegetation of the various disturbance areas along the road. <br />II. PLANT GROWTH MEDIA: Over much oP the disturbed area along the <br />' roadway, the current surface material appears at least somewhat capa.bie <br />of adequate revegetation without the application of any addit[onal growth <br />' media. This is evidenced by the common occurrence of various specie; oP <br />plants growing in the existing material. <br />' The primary exceptions to this occurs where limestone processing <br />' waste fines are exposed on the surface or the surface material is <br />primarily composed of large rocks mixed with a limited amount of fires. <br />Past experience at this quarry operation and other operations has shown <br />' that the locations where limestone fines are present are capable of <br />supporting good growth, but achieving that growth is difficult and in <br />' most instances unsuccessful to an extent required by the law or 'the <br />desires and expectations of the company.
