- (a) General. A general description of the surface drainage plan for the proposed operation shall be provided. This description shall include, but not be limited to, description of proposed handling of off-site drainage entering the mining permit area, mining permit area sediment control, measures to prevent CCB from entering water leaving the mining permit area, and general description of measures to prevent non-CCB contaminants from entering storm water leaving the mining permit area.(b) Surface water monitoring plan. A plan for surface water monitoring shall include the following parameters to be analyzed annually and semi-annually:(1) Ash site surface water testing parameters: annually(A) pH(B) TDS(C) TSS(D) Specific conductance(E) Sulfates(F) Temperature(G) Total iron(H) Total manganese(I) Arsenic(J) Barium(K) Cadmium(L) Chromium (total)(M) Lead(N) Fluoride(O) Selenium(P) Flow in streams, flow rate of discharges of impoundments(Q) Impoundment freeboard(R) Impoundment depth(S) Alkalinity(T) Chloride(U) Nitrate(V) Nitrite(W) Ammonia(X) Aluminum(Y) Calcium(Z) Sodium(AA) Additional parameters may be required by the Department based on conditions at the site.(2) Ash site surface water testing parameters: (Semi-annually for active sites, inactive sites and sites in temporary cessation status as set forth in 30-5-22 complying with 30-5-11)(A) pH(B) TDS(C) TSS(D) Specific conductance(E) Sulfates(F) Temperature(G) Flow in streams, flow rate of discharges of impoundments(H) Impoundment freeboard(I) Impoundment depth(J) Alkalinity(K) Chloride(L) Nitrate(M) Nitrite(N) Ammonia(O) Aluminum(P) Calcium(Q) Sodium(R) Additional parameters may be required by the Department based on conditions at the site.(3) CKD site surface water testing parameters: annually;(A) Surface water elevation(B) Temperature(C) pH(D) Specific conductance(E) Potassium(F) Sodium(G) TDS(H) Chloride(I) Sulfates(J) Antimony(K) Arsenic(L) Barium(M) Beryllium(N) Cadmium(O) Chromium (total)(P) Lead(Q) Mercury(R) Nickel(S) Selenium(T) Silver(U) Thallium(V) Alkalinity(W) Aluminum(X) Calcium(Y) TSS(Z) Additional parameters may be required by the Department based on conditions at the site.(4) CKD site surface water testing parameters: semi-annually(A) Surface water elevation(B) Temperature(C) pH(D) Specific conductance(E) TDS(F) Chloride(G) Sulfates(H) Potassium(I) Sodium(J) Alkalinity(K) Aluminum(L) Calcium(M) TSS(N) Additional parameters may be required by the Department based on the conditions at the site.(5) Water quality monitoring shall continue for permits issued after July 1, 2011, at the same frequency stated above for a minimum of 5 years after final placement of CCBs at the site. The Department may require more frequent or longer water quality monitoring if the results of water quality monitoring indicate that contamination may be occurring.(c) Ground water monitoring plan. A plan for ground water monitoring shall include the following parameters to be analyzed annually and semi-annually:(1) Ash site ground water testing parameters: annually(A) pH(B) TDS(C) Specific conductance(D) Sulfates(E) Temperature(F) Total iron(G) Total manganese(H) Arsenic(I) Barium(J) Cadmium(K) Chromium (total)(L) Lead(M) Fluoride(N) Selenium(O) Depth to water(P) Alkalinity(Q) Chloride(R) Nitrate(S) Nitrite(T) Ammonia(U) Aluminum(V) Calcium(W) Sodium(X) TSS(Y) Additional parameters may be required by the Department based on conditions at the site.(2) Ash site ground water testing parameters: (Semi-annually for active sites, inactive sites and sites in temporary cessation status as set forth in Section 30-5-22 complying with 30-5-11 )(A) pH(B) TDS(C) Specific conductance(D) Sulfates(E) Temperature(F) Depth to water(G) Alkalinity(H) Chloride(I) Nitrate(J) Nitrite(K) Ammonia(L) Aluminum(M) Calcium(N) Sodium(O) TSS(P) Additional parameters may be required by the Department based on conditions at the site.(3) CKD site ground water testing parameters: annually(A) Depth to water(B) Temperature(C) pH(D) Specific conductance(E) TDS(F) Chloride(G) Sulfates(H) Potassium(I) Sodium(J) Antimony(K) Arsenic(L) Barium(M) Beryllium(N) Cadmium(O) Chromium (total)(P) Lead(Q) Mercury(R) Nickel(S) Selenium(T) Silver(U) Thallium(V) Alkalinity(W) Aluminum(X) Calcium(Y) TSS(Z) Additional parameters may be required by the Department based on conditions at the site.(4) CKD site ground water testing parameters: semi-annually(A) Depth to water(B) Temperature(C) pH(D) Specific conductance(E) TDS(F) Chloride(G) Sulfates(H) Potassium(I) Sodium(J) Alkalinity(K) Aluminum(L) Calcium(M) TSS(N) Additional parameters may be required by the Department based on conditions at the site.(5) Water quality monitoring shall continue for permits issued after July 1, 2011, at the same frequency as stated above for a minimum of 5 years after final placement of CCB at the site. The Department may require more frequent or longer water quality monitoring if the results of water quality monitoring indicate that contamination may be occurring.
