Bioso idc par m t r (on 'Hued) (iii) Samples taken in compliance with the monitoring requirements specified above shall be taken at the following locations: 1) For biosolids stability/volatile solids reduction, samples shall be taken before digestion and dewatering (or other stabilization processes) and afrer the biosolids has- been digested and/or dewatered (or otherwise stabilized) but prior to transport or disposal; 2) For all other parameters, samples shall be taken afrer digestion and/or dewatering (or other stabilization processes) but prior to transport or disposal. All samples shall be representative of the biosolids stream being sampled. Beneficial Use" means the use of nutrients and/or moisture in the biosolids to act as a soil conditioner or low grade fertilizer for the promotion of vegetative growth on land. d) An~ytical and Sa_mplinp Methods for Motitorine Sample collection, preservation and analysis shall be performed in a manner consistent with the requirements of the Biosolids Regulations, 64 (SCCR 1002-64) and/or other criteria specified in this permit. Metals analyses aze to be performed using method SW 846 with samples prepazed in accordance with method 3050. The methods aze also described in the latest version of the EPA Region VIII Biosolids Management Handbook. . e) Records ° Biosolids which aze Class A with respect to pathogens and which meet the monthly pollutant concentration limits identified in Part I.A.2.a) shall comply with the recordkeeping requirements identified in sections 4.e)(I)(1) through 4.e)(I)(3), below. If the biosolids aze Class B with respect to pathogens, or if any pollutant limited in Part I.A.2.a) increases to the point where the biosolids no longer meet the monthly average pollutant :concentration limits in Part I.A.2.a), the permittee shall comply with all of the recordkeeping requirements identified below: (I) The permittee is required to have access to the following information for at least 5 yeazs: (1) Test results showing the concentration of each pollutant in Part I.A.2.a); (2) A description of how the pathogen reduction requirements in Part I.A.2.b) were met; _ (3) A description of how the vector amaction reduction requirements in Part I.A.2.c) were met; (4) A description of how the management practices in Part I.A.2.e) were me[ (if necessary); (5) A description of how the site restrictions in Part I.A.2.b) were met (if necessary); and (6) The following certification statement: "I certify under the penalty of law, that the pathogen requirements in Part I.A.2.b), one of the vector attraction reduction alternatives in Part I.A.2.c), the managemen[ practices in Part I.A.2.d) (if necessary) and the site restrictions in Part I.A.2.b) (if necessary) have been met. This determination _ has been made under my duec[ion and supervision in accordance with the system designed [o assure _ that qualified personnel properly gather and evalua[e the information used to determine that the pathogen requirements, the vector attraction reduction requiremen[s, the management practices and the - site restrictions have been met. I am aware tha[ [here are significant penalties for false certification including the possibility of imprisonmen[." . + AmendmentNo. 1 Issued .i'UN 7 8 10QA Effective ~y~ J i ~,""[J~-~ ;~,:
